+ <h2>1. ModCluster - Technology overview</h2>
+
+ <p>ModCluster is next generation clustering solution for connecting native
+ web servers and application servers.
+ The major advantage of ModCluster is dynamic configuration that is done
+ by ModClusterService and propagated to all web servers.
+ </p>
+ <p>ModClusterService is dedicated application embedded inside Application Server
+ or an stand-alone application. It's main duty is to configure and manage front-end
+ web server(s) and to track various objects in application server(s).
+ </p>
+ <img src="./images/o2m.png">
+ <p class="image"><strong>Figure 1.</strong> Typical configuration with Web server in front of
+ multiple application servers.
+ </p>
+ <br/>
+ <p>ModClusterService connects to the ModCluster using HTTP or HTTPS protocol
+ and both configures and monitors Apache Httpd Web server.
+ </p>
+ <p>ModClusterService is capable of managing multiple Web servers in front.
+ Any number of web servers and be defined. Their status are checked at regular
+ intervals and ModClusterService can act accordingly
+ </p>
+ <img src="./images/m2m.png">
+ <p class="image"><strong>Figure 2.</strong> Multiple Web servers in front of
+ multiple application servers.
+ </p>
+ <br/><br/>
+ <h2>1.2. Graceful node shutdown</h2>
+ <p>When an Application Server Stop event is received from one of the Nodes
+ that are member of the cluster, or direct command to Stop the server is
+ made by Administrator the ModClusterService informs all Web Servers he is
+ aware being operable to Stop serving new requests.
+ </p>
+ <img src="./images/commstop.png">
+ <p class="image"><strong>Figure 3.</strong> Node Stop event handling.
+ </p>
+ <p>Existing requests that have session affinity information present will
+ still continue to be served by that particular node. This allows to
+ gracefully shutdown particular node for maintenance.
+ </p>
+ <br/><br/>
+ <h2>1.3. Node disable</h2>
+ <p>Unlike graceful shutdown, Disable immediately shutdowns the connections from
+ web servers to that particular node.
+ </p>
+ <img src="./images/commshutdown.png">
+ <p class="image"><strong>Figure 4.</strong> Node Disable event handling.
+ </p>
+ <p>This operation is usually issued after graceful shutdown and after
+ all active sessions timed out, or it can be used as a way of putting Nodes
+ down in case there is session replication in place among application servers,
+ meaning that users will not loose their sessions.
+ </p>
+ <br/><br/>
+ <h2>1.4. Communication errors</h2>
+ <p>If there is communication error between particular web server and one of the
+ Application servers the ModClusterService will be informed about that on next
+ regular status interval query.
+ </p>
+ <img src="./images/connerr.png">
+ <p class="image"><strong>Figure 5.</strong> Communication error handling.
+ </p>
+ <p>Reasons for communication errors can be caused by many reasons.
+ The ModCluster service will figure out the reason, and if the reason
+ is unrecoverable it will inform all other Web servers that one of the
+ nodes is down. Multiple handling scenarios can then be employed from
+ setting up the fail-over node, to informing the administrator via e-mail
+ </p>
+ <br/><br/>
+ <h2>1.5. Node discovery</h2>
+ <p>ModeClusterServices uses JBossClustering to discover new nodes that
+ have joined the cluster. In case of such event the front-end Web servers
+ are informed about that and node configuration is added.
+ </p>
+ <img src="./images/commnew.png">
+ <p class="image"><strong>Figure 6.</strong> Node discovery handling.
+ </p>
+ <br/><br/>
+ <br/><br/>
+ <h2>2. ModCluster - Basic design</h2>
+ <p>ModCluster basic design is shown on the following picture
+ </p>
+ <img src="./images/genarch.png">
+ <p class="image"><strong>Figure 7.</strong> Basic Architecture.
+ </p>
+ <p>Shared memory is used to dynamically configure the Apache Httpd so it can
+ use zero-configuration presumption of ModCluster.
+ The core engine for ModClusterProxy is <strong>mod_proxy</strong>, and
+ supported Apache Httpd versions are <strong>2.2.3</strong> and up.
+ </p>
+ <br/><br/>
+ <h2>2.1. Startup</h2>
+ <p>Upon startup ModCluster service uses configuration and connects to the
+ Apache Httpd Web server that has loaded ModCluster native module.
+ </p>
+ <img src="./images/configzero.png">
+ <p class="image"><strong>Figure 8.</strong> ModCluster startup.
+ </p>
+ <p>Apache Httpd server on startup has empty configuration, so any
+ user request will produce 404 until ModClusterService configures the
+ ModCluster.
+ </p>
+ <br/><br/>
+ <h2>2.2. Initial Configuration</h2>
+ <p>ModClusterService discovers the members of the cluster and all
+ additional information like defined Hosts and deployed Applications.
+ </p>
+ <img src="./images/configinit.png">
+ <p class="image"><strong>Figure 9.</strong> ModCluster initialization.
+ </p>
+ <p>ModClusterService has the full view of the cluster that
+ is managed, so it can decide what configuration will be send
+ to the Web server. It can use some sort of GUI or any other
+ type of configuration for that purpose.
+ </p>
+ <br/><br/>
+ <h2>2.3. Undeploying applications</h2>
+ <p>When the undeploy event is received from the particular
+ Node that information is send to the Web server.
+ </p>
+ <img src="./images/configupdate.png">
+ <p class="image"><strong>Figure 10.</strong> Undeploy/Stop Application.
+ </p>
+ <p>ModCluster can handle undeploy events in various ways depending
+ on the instructions received from ModClusterService.
+ If the Undeploy will be followed by Deploy (Redeploy event)
+ it may queue the requests until the application is deployed
+ again.
+ </p>
+ <br/><br/>
+ <h2>2.4. Deploying new applications</h2>
+ <p>When the deploy event is received from the particular
+ Node that information is send to the Web server.
+ </p>
+ <img src="./images/configdeploy.png">
+ <p class="image"><strong>Figure 11.</strong> Deploying New applications.
+ </p>
+ <p>When new application is deployed to the cluster that information
+ is send to all web servers and is ready to be used.
+ ModClusterManager adds that information to the shared memory,
+ and ModClusterProxy can use that info to route the requests
+ to the newly deployed application.
+ </p>
+ <br/><br/>
+ <br/><br/>
+ <h2>3. ModCluster Management Protocol -- MCMP/1.0</h2>
+ <p>ModCluster uses HTTP/1.1 protocol for the management of clustering
+ properties, creation and management of cluster nodes, application
+ name space manipulation, and load balancing.
+ Complete description of the protocol can be found in the RFC-like form
+ at <a href="http://jira.jboss.com/jira/secure/attachment/12319781/rfc5501.txt">JBoss Jira</a>.
+ </p>
+ <p>ModClusterManager parses HTTP requests at the predefined location.
+ By default, the listening location is <code>/modclustermanager</code>.
+ However the administrator can for increased security use different
+ naming and protect this url inside Apache Httpd <code>Location</code> directive:
+ </p>
+ <pre>
+ <Location /manager>
+ SetHandler ModClusterManagerHandler
+ Order Deny,Allow
+ Allow from 192.168.0
+ </Location>
+ </pre>
+ <p>For even more enhanced security certain operations can be limited, allowing
+ multiple MCMP capable clients to gather data and only certain to manage
+ the ModCluster.
+ </p>
+ <pre>
+ <Location /manager/info>
+ SetHandler ModClusterManagerHandler
+ Order Deny,Allow
+ Allow from All
+ </Location>
+ </pre>
+ <pre>
+ <Location /manager/config>
+ SetHandler ModClusterManagerHandler
+ Order Deny,Allow
+ Allow from 192.168.0
+ </Location>
+ </pre>
+ </p>
+ <p>Major protocol presumption is the single header value named
+ <code>Server-Resource</code> that <b>must</b> be present for each
+ management request.
+ <br/>
+ The format of the <code>Server-Resource</code> header variable
+ corresponds to the HTTP State Management Mechanism <code>rfc2109</code>,
+ or commonly known as Cookie specification.
+ </p>
+ <p>This allows to go beyond request query size limitations and also there
+ is no need for additional query parameter encoding that would have to
+ be used for query like processing.
+ </p>
+ <p>Each management request produces reply with <code>text/plain</code>
+ mime type, and manager uses the body of the reply as an response
+ to the management request
+ </p>
+ <br/><br/>
+ <h2>3.1. Protocol commands</h2>
+ <p>Each management request must define operation or command that ModCluster must
+ accomplish. If the operation is successful the ModCluster responds with
+ <code>OK</code> and sends any additional data for that command.
+ </p>
+ <p>Commands that MCMP protocol supports are:
+ <ul>
+ <li><strong>INFO</strong>
+ command causes the manager to gather the information about
+ the specific resource on the server.
+ </li>
+ <br/>
+ <li><strong>ENABLE</strong>
+ command causes the manager to enable the specific resource
+ on the server.
+ </li>
+ <br/>
+ <li><strong>DISABLE</strong>
+ command causes the manager to disable the specific resource
+ on the server.
+ Depending on the resource object type the DISABLE command has different
+ consequences. For Node object it will disable further acceptance of
+ the request that does not carry the session affinity mark information,
+ while preserving the ones that carry
+ the session affinity mark.
+ </li>
+ <br/>
+ <li><strong>STOP</strong>
+ command causes the manager to stop the specific resource
+ on the server.
+ </li>
+ <br/>
+ <li><strong>DELETE</strong>
+ command causes the manager to completely remove the specific
+ resource on the server.
+ </li>
+ <li><strong>CONFIG</strong>
+ command causes the manager to create or update the specific
+ resource on the server.
+ </li>
+ </ul>
+ </p>
+ <p>Commands are case insensitive and can be send to the manager in various ways:
+ <ul>
+ <li>As query argument<br/>
+ <pre>
+ GET /modclustermanager?info HTTP/1.1
+ Host: localhost
+ Server-Resource: Host/foo
+ </pre>
+ </li>
+ <li>As <code>Server-Command</code> header<br/>
+ <pre>
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Command: info
+ Server-Resource: Host/foo
+ </pre>
+ </li>
+ </ul>
+ </li>
+ <li>As <code>Command</code> section inside <code>Server-Resource</code><br/>
+ <pre>
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Resource: Command=info; Host/foo
+ </pre>
+ </li>
+ <li>As last part or Url path<br/>
+ <pre>
+ GET /modclustermanager/info HTTP/1.1
+ Server-Resource: Host/foo
+ </pre>
+ </li>
+ </ul>
+ </p>
+ <br/><br/>
+ <h2>3.2. Info command</h2>
+ <p>Info command is used to gather the info about the web server resources.
+ Each resource carries his own set of attributes that are contained in
+ the response message one line at a time
+ </p>

+ <h2>3.4. Disable command</h2>
+ <p>Disable command has the same format as Enable command.
+ The only difference is that disable command disables the
+ resource making it unavailable for any new processing.
+ </p>
+ <br/><br/>
+ <h2>3.5. Stop command</h2>
+ <p>Stop command has the same format as Enable command.
+ The only difference is that stop command disables the

+ <br/><br/>
+ <h2>4.1. Database model</h2>
+ <p>Diagram on the Figure 13. shows basic database model for few core objects
+ </p>
+ <img src="./images/bdbm.png">
+ <p class="image"><strong>Figure 13.</strong> Object database model.
+ </p>
+ <p>Database is stored in shared memory so that it is directly accessible by all
+ child processes in Web server. Each table is stored in separate shared memory
+ and each record is of fixed size. This makes memory usage not fully optimized,
+ but allows very fast record access.
+ </p>
+ <p>Each table <code>Id</code> field is not actually stored in the table, but rather
+ it represents the record number in the table. Referencing tables contain that
+ record number as foreign record key. The tables are not indexed, however some
+ tables are backed up by in-memory hash table for faster access.
+ Before each request, inside request post processing phase, ModCluster module
+ checks the atomic time stamps of each table, and if they do not match the
+ internal hash table index is recreated. This allows both optimal key based
+ access and does not require full blown backed database.
+ </p>
+ <p>Internal Hash tables are created on demand, and the cause for their creation is
+ the size of the table and length of the key value. Those options are compile time
+ defined, and in general the table is not indexed unless its size gets really big
+ (thousands of records). In most use cases those numbers won't be that large, and
+ simple sequential scan is used instead.
+ </p>
+ <br/><br/>
+ <h2>4.2. Host table initialization</h2>
+ <p>Diagram on the Figure 14. shows the data flow diagram of Host tables that is
+ executed on Web server startup.
+ </p>
+ <img src="./images/starthostdf.png">
+ <p class="image"><strong>Figure 14.</strong> Web server startup.
+ </p>
+ <p>When the Web server is started or fully restarted it contains empty configuration
+ as shown on the Figure 9. However Host and Server tables are created on the startup
+ containing objects that are defined inside native Web server configuration.
+ </p>
+ <p>Host table is loaded with all virtual host definitions by default.
+ However the administrator of the web server can use specific directives
+ in case the Web server is used for large ISP providers with thousands of
+ Virtual Host definitions.
+ The only reason for using those directives is for limiting the memory
+ usage if there will be no need to map requests from each Virtual Host to the
+ Application server cluster. Two configuration directives exist for this
+ reason <code>ModClusterHostCopy</code> and <code>ModClusterEnable</code>
+ The first directive if set to <code>Off</code> will not create any Host
+ object except default Host, and the second if defined inside Virtual Host
+ and set to <code>On</code>will create Host record for that virtual host.
+ </p>
+ <br/><br/>
+ <h2>4.3. Host configuration</h2>
+ <p>Diagram on the Figure 15. shows the data flow diagram of Host tables when
+ the <strong>Config</strong> command is executed.
+ </p>
+ <img src="./images/confighostdf.png">
+ <p class="image"><strong>Figure 15.</strong> Host object configuration.
+ </p>
+ <p>Host configuration operates on two main levels, Host itself and Alias.
+ Host object contains actual data and is stored directly in HostList table.
+ Both Host and Alias are stored in Host table, with later having table
+ self reference key to the Host.
+ This allows to have a single table for both Host and Aliases, but since
+ Aliases are dependent on the Host, any operation on the Host will propagate
+ to all its aliases. HostList table is helper table because Host and its
+ Aliases always point to the same data. Their only difference is in the
+ name, so this table is used to lower down the overall memory usage.
+ </p>
+ <p>Host Config like any other config directive can operate on wildchar
+ principle, meaning that it will be executed for all Host objects matching
+ the given expression. Expression evaluator is modified <code>fnmatch</code>
+ Posix function, available from the Apache APR library.
+ </p>
+ <pre>
+ ModClusterService -> ModClusterManager
+
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Command: Config
+ Server-Resource: Host/www.*.com; KeepAlive=Off
+
+
+ ModClusterManager -> ModClusterService
+
+ HTTP/1.1 200 OK
+ Server: Apache/2.2.8 (Unix)
+ Content-Length: 4
+ Keep-Alive: timeout=5, max=100
+ Connection: Keep-Alive
+ Content-Type: text/plain
+
+ OK
+ </pre>
+ <p>The upper example will disable <code>KeepAlive</code> in Web Server
+ for all virtual host requests matching <code>www.*.com</code>. The Command
+ will actually set the <code>KeepAlive</code> attribute to <code>Off</code>
+ for each Host table entry. Since the operation is performed on Host table
+ and KeepAlive attribute is held in HostList table this attribute will be
+ applied for both Host and all of his Aliases. Likewise if one of the Aliases
+ matches the <code>www.*.com</code> pattern it will cause the attribute change
+ in both parent Host and all other Aliases for that Host.
+ </p>
+ <br/><br/>
+ <h2>4.4. Application configuration</h2>
+ <p>Diagram on the Figure 16. shows the data flow diagram of Application table when
+ the <strong>Config</strong> command is executed.
+ </p>
+ <img src="./images/configappdf.png">
+ <p class="image"><strong>Figure 16.</strong> Application object configuration.
+ </p>
+ <p>Applications are contained inside Host object and cannot live outside the
+ Host as stand-alone entity. If the Host was not provided with the Config
+ command default Host is selected. Default host <code>_default_</code> is
+ the Web servers default host that matches the Server object ServerName attribute.
+ </p>
+ <p>Application name uniquely identifies application within Host and it defaults
+ to <code>Url</code> field. However the application can be referenced by name
+ attribute as convenient method for accessing application object. Application
+ command SubType is always url unless enclosed inside underscore characters
+ <code>'_'</code> in which case SubType is assumed to be application name not its url.
+ There is no need to add the leading slash for the Application Url because it is assumed.
+ </p>
+ <p>When new Host object is created default Application with empty Url is created
+ for that Host as well, but it is initially disabled. This Application object
+ corresponds to Application server Default Context. This Application has
+ empty Url that corresponds to Application server Context object with
+ <code>path=""</code>. Its name is internally set to <code>_default_</code>,
+ and can be later referenced as <code>Application/_default_</code>.
+ If later used as part of Application Config command the ModCluster will not need
+ to create that object again, so this is basically performance optimization.
+ </p>
+ <p>Operations on the Application object can be performed using wildchar causing
+ execution on all applications matching the expression. However attributes for
+ such operation must not be application object unique.
+ </p>
+ <pre>
+ ModClusterService -> ModClusterManager
+
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Command: Config
+ Server-Resource: Host/www.*.com; Application/*/production; State=S
+
+
+ ModClusterManager -> ModClusterService
+
+ HTTP/1.1 200 OK
+ Server: Apache/2.2.8 (Unix)
+ Content-Length: 4
+ Keep-Alive: timeout=5, max=100
+ Connection: Keep-Alive
+ Content-Type: text/plain
+
+ OK
+ </pre>
+ <p>The upper example set State of all Applications to <code>S (Stopped)</code>
+ which Url matches <code>/*/production</code> and which are contained
+ in Hosts which ServerName matches <code>www.*.com</code>.
+ </p>
+ <p>Returned value for newly created applications is its numeric record <code>Id</code>
+ and can be later used when referencing object if the SubType is enclosed
+ inside braces. The Id of each object within its type is guaranteed to be
+ unique, so this allows to have multiple objects sharing the same name
+ while still being uniquely identified inside ModCluster.
+ </p>
+ <pre>
+ ModClusterService -> ModClusterManager
+
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Command: Config
+ Server-Resource: Application/(1234); State=S

+ <h2>4.5. Member configuration</h2>
+ <p>Diagram on the Figure 17. shows the data flow diagram of Member table when
+ the <strong>Config</strong> command is executed.
+ </p>
+ <img src="./images/configmemberdf.png">
+ <p class="image"><strong>Figure 17.</strong> Member object configuration.
+ </p>
+ <p>Member object corresponds to the physical Application server instance.
+ Actually it corresponds to the <code>Connector</code> element in Application
+ Server configuration and represents the physical connection to the
+ Application server. The reason for such design comes from old mod_jk and
+ mod_proxy limitations using Ajp connections. They have tendency for high
+ connection count, so this enable to create fail-over to the same physical
+ Application Server instance but on other usually Http connector.
+ </p>
+ <p>Like on any other Resource object the operations on the Member object can
+ be done using wildchar causing to execute the Config on all Members matching
+ the given expression. Of course this is like for Application or Host object limited
+ only to the non unique attributes
+ </p>
+ <p>Member can be assigned to Balancer object, and if not explicitly specified
+ when added it will be added to the default Balancer object that is created
+ on startup. Member can be referenced by multiple Balancer objects allowing
+ different balancer algorithms on application name space basis.
+ </p>
+ <br/><br/>
+ <h2>4.6. Balancer configuration</h2>
+ <p>Diagram on the Figure 18. shows the data flow diagram of Balancer table when
+ the <strong>Config</strong> command is executed.
+ </p>
+ <img src="./images/configbalancerdf.png">
+ </a>
+ <p class="image"><strong>Figure 18.</strong> Balancer object configuration.
+ </p>
+ <p>Balancer object is responsible for routing requests to one of its Member
+ objects. On system startup a single default Balancer object is created
+ and it is used for all Members unless explicitly specified during Member
+ configuration. Members can be referenced by multiple balancers but not
+ by default and some other balancers. If the member is referenced from
+ non default Balancer it will be removed from the default Balancer object.
+ </p>
+ <p>Balancer can contain reference to Application objects and Host objects.
+ Host object is special kind of relationship resulting in referencing
+ all Application objects contained inside Host object. This allows that
+ new Applications deployed inside specific Host get automatically referenced
+ by the specified Balancer object.
+ </p>
+ <pre>
+ ModClusterService -> ModClusterManager
+
+ GET /modclustermanager HTTP/1.1
+ Host: localhost
+ Server-Command: Config
+ Server-Resource: Balancer/productionCluster; Host/production.*; Member/node[1-7];
+
+
+ ModClusterManager -> ModClusterService
+
+ HTTP/1.1 200 OK
+ Server: Apache/2.2.8 (Unix)
+ Content-Length: 4
+ Keep-Alive: timeout=5, max=100
+ Connection: Keep-Alive
+ Content-Type: text/plain
+
+ OK|Id
+ </pre>
+ <p>The upper example will create (if it wasn't alread, returning Id of the newly created)
+ Balancer object and add reference to it for all Applications that are
+ contained in each Host which name matches the <code>production.*</code>
+ expression, and add reference to Member objects which name matches
+ the <code>node[1-7]</code> expression. As can be seen that simple Config
+ command can result in large number of internal objects created and referenced.
+ Deploying new applications to any <code>production.*</code> Host will automatically
+ reference that Application to this Balancer object.
+ </p>
+ <br/><br/>
+ <h2>4.7. Connection Pool configuration</h2>
+ <p>Diagram on the Figure 19. shows the data flow diagram of Connection Pool
+ the <strong>Config</strong> command for Member is executed.
+ </p>
+ <img src="./images/connpooldf.png">
+ <p class="image"><strong>Figure 19.</strong> Connection Pool management.
+ </p>
+ <p>For each Member if not specifically configured during
+ creation ModCluster creates a pool of empty connections with maximum size
+ equal to Web server's maximum limit. For threaded servers this value
+ equals to <code>MaxThreadsPerChild</code> configuration directive in Apache
+ Httpd. This pool is created for each child process the Web server
+ creates for serving requests. Updating this value and dynamically changing
+ it from already set or default value is done both by Configure
+ Member command and by maintenance thread or on first request, which ever
+ comes first. If the value is lower then already defined, all extra
+ connections that doesn't currently serve requests are closed. If then
+ extra connections are currently serving requests, they are closed when
+ those request are finished.
+ </p>
+ <br/><br/>
+ <br/><br/>
+ <h2>5. Communication Error Handling</h2>
+ <p>Diagram on the Figure 20. shows how ModProxy deducts connection errors.
+ </p>
+ <img src="./images/connerrordf.png">
+ <p class="image"><strong>Figure 20.</strong> Connection Error algorithm.
+ </p>
+ <p>ModCluster uses <code>Ping/Pong</code> feature of the <code>Ajp</code>
+ protocol or modified <code>OPTIONS</code> request for <code>Http</code>
+ protocol to verify the physical connection state before sending actual request
+ to the Member itself. This allows to fail over to another cluster Member
+ if the member has connection errors.
+ However various actions can be done when such error occurs, from
+ simply failing over to another node, to reconnect attempts, or any
+ combination of them.
+ </p>
+ <p>For Http(s) protocol needs to be developed special <code>OPTIONS</code>
+ filter that will allow <code>HTTP/1.1 with KeepAlive</code>.
+ <em>Default Tomcat implementation doesn't allow KeepAlive for OPTIONS request
+ so this either needs to get revised or create a new Filter for
+ ModCluster usage</em>.
+ </p>
+ <p>ModCluster will mark the Member as in Error state only when there is no
+ active connections present. In other case it will cause the same
+ behavior as for Connection Poll busyness. The reason for such behavior is
+ probability that Application Server cannot accept any new connections
+ since there is already some number of requests currently executing.
+ </p>
+ <br/><br/>
+ <h2>5.1. Unattended Connection Monitoring</h2>
+ <p>Diagram on the Figure 21. shows how ModProxy monitors the connections
+ for availability.
+ </p>
+ <img src="./images/upingdf.png">
+ <p class="image"><strong>Figure 21.</strong> Connection state monitoring.
+ </p>
+ <p>Maintenance thread that is created inside each Web server child process
+ on regular time interval checks the health of all connections in the
+ Connection poll. He does that only for connections that are not
+ active (currently serving requests) and which were inactive for a
+ certain amount of time. This solves two major problems found in mod_jk
+ and current mod_proxy. Firewall shutting down inactive connections and
+ burst load delays.
+ </p>
+ <p>In case the Member was in error state ModCluster will try to reconnect
+ to the Application server creating new connection if needed. This is
+ major difference compared with mod_jk and mod_proxy and is called
+ <b>Active Recovery</b>.
+ <br/>
+ <br/>
+ <img src="./images/connconcepts.png">
+ <p class="image"><strong>Figure 22.</strong> Connection states.
+ <p>Connection between ModCluster and Application server has two major states
+ <code>Active Request</code> and <code>Active Transaction</code>.
+ During Active Request state management thread cannot access the Connection
+ and it is presumed as active. Active Transaction can contain multiple
+ Request cycles. The KeepAliveTimeout depends on two things, if not set
+ directly for a Connector it inherits the KeepAliveTimeout of the Web server,
+ corresponding to the client timeout. If set it usually corresponds to the
+ connectionTimeout of the Application server's Connector. ModCluster can
+ close the connection if there were no Active Requests inside this time
+ interval. There is no need to check the connections since we are sure it
+ was already closed by the Application server.

+
+
+1 Introduction
+
+1.1 Purpose
+
+ This document describes an extension to the HTTP/1.1 protocol that
+ allows clients to perform remote clustering management operations.
+ This extension provides a coherent set of methods, headers, request
+ entity body formats, and response entity body formats that provide
+ operations for:
+
+ Members: The ability to create, remove, update and query information
+ about cluster members, such as their node address, session route, etc.
+ Also, the ability to link Applications of any media type to related
+ members.
+
+ Applications: The ability to create sets of mapped Applications and to
+ establish relationship between applications and members.
+
+1.2 Requirements
+
+ The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+ "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
+ document are to be interpreted as described in RFC 2119 [34].
+
+ An implementation is not compliant if it fails to satisfy one or more
+ of the MUST or REQUIRED level requirements for the protocols it
+ implements. An implementation that satisfies all the MUST or REQUIRED
+ level and all the SHOULD level requirements for its protocols is said
+ to be "unconditionally compliant"; one that satisfies all the MUST
+ level requirements but not all the SHOULD level requirements for its
+ protocols is said to be "conditionally compliant."
+
+

+RFC 5501 MCMP March 2008
+
+
+1.3 Terminology
+
+ This specification uses a number of terms to refer to the roles
+ played by participants in, and objects of, the MCMP communication.
+
+ connection
+ A transport layer virtual circuit established between two programs
+ for the purpose of communication.
+
+ client
+ A program that establishes connections for the purpose of sending
+ requests.
+
+ message
+ The basic unit of HTTP communication, consisting of a structured
+ sequence of octets matching the syntax defined in HTTP/1.1
+ specification [RFC2068].
+
+ request
+ An HTTP request message, as defined in HTTP/1.1 specification
+ [RFC2068].
+
+ response

+ An application program that accepts connections in order to
+ service requests by sending back responses. Any given program may
+ be capable of being server; our use presumes it is Web server.
+
+ member
+ A dynamic resource in the web server that connects to the
+ remote backend application server node and proxies the requests
+ back and forth.
+

+
+
+ node protocol
+ The protocol used for communication between member and node.
+ Supported protocols are Apache Jserv Protocol (AJP) version
+ 1.3 as described in AJP protocol specification
+ [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html],
+ HTTP 1.1 [RFC2068] and HTTPS [RFC2818].
+
+ application
+ A network data object or service that can be identified by a URI,
+ as defined n HTTP/1.1 specification [RFC2068] and provided by
+ the node.
+
+ cluster
+ A set of nodes that creates an management entity; our
+ use presumes they provide the same set of applications.
+
+ cluster group
+ A set of nodes in the cluster that shares the session replication
+ between them; our use presumes they have "buddy replication"
+ in place.
+
+ balancer
+ An static resource in the web server that consists of the list
+ of members. Balancer chooses the best member for servicing the
+ client request from the cluster or cluster group.
+
+ manager
+ An static resource in the web server that receives protocol
+ requests and manages the resources in the web server.
+
+ administrator
+ An application or applications in the cluster that communicates
+ with the manager using MCMP protocol. Its main usage is to
+ provide the manager with list of nodes, clusters, cluster groups
+ and applications together with the balancer information needed
+ for selecting the best node within the cluster for servicing the
+ client request.

+
+
+1.4 Overall Operation
+
+ The MCMP protocol is a request/response protocol. An administrator
+ sends a request to the web server in the form of a HTTP request method,
+ URI, and protocol version, followed by a set of headers containing request
+ modifiers, node information, etc. The manager responds with a status line,
+ including the message's protocol version and a success or error code,
+ followed by a text/plain MIME-like message containing server information,
+ entity metainformation, and possible entity-body content.
+
+ Client--->Balancer--->1*Member---->1*Node
+ | | |
+ +---------Manager<---->1*Administrator

+ The figure above shows the typical relation between participants
+ in the system.

+
+2 Notational Conventions and Generic Grammar
+
+ The Notational Conventions and Generic Grammar used is the one specified
+ in the HTTP 1.1 protocol specification RFC2068 [2].
+
+3 Protocol Parameters
+
+3.1 HTTP Version
+
+ MCMP uses HTTP 1.1 protocol version as defined in HTTP/1.1 specification
+ [RFC2068]. For the increased security the protocol used can be HTTP over
+ TLS or usually known as HTTPS [RFC2818].
+
+3.2 MCMP Version
+
+ The current MCMP version according to this rfc is "1.0".
+ MCMP uses a "<major>.<minor>" numbering scheme to indicate versions
+ of the protocol.
+
+ The version of an MCMP message is indicated by an MCMP-Version field
+ in the first line of the message.
+
+ MCMP-Version = "MCMP" "/" 1*DIGIT "." 1*DIGIT
+
+ Note that the major and minor numbers MUST be treated as separate
+ integers and that each may be incremented higher than a single digit.
+ Thus, MCMP/2.4 is a lower version than MCMP/2.13, which in turn is
+ lower than MCMP/12.3. Leading zeros MUST be ignored by recipients and
+ MUST NOT be sent.
+
+3.3 HTTP Methods
+
+ MCMP uses GET HTTP method for management and OPTIONS method for
+ determining the validity of the connection between member and node.
+
+
+
+Turk, et. al. Standards Track [Page 6]
+
+RFC 5501 MCMP March 2008
+
+
+
+3.4 MCMP URL
+
+ Each mcmp requests MUST be an valid http request with URI
+ compliant to the RFC2068 [3.2]. The query MAY be present to
+ specify the command. In case the query is not present then the
+ administrator MUST provide the Server-Command header with corresponding
+ command value or use the appropriate HTTP method.
+ This section defines the scheme-specific
+ syntax and semantics for mcmp URLs.
+
+ mcmp_URL = "http:" "//" host [ ":" port ] abs_path [ cmd_path | "?" query ]
+
+ If the port is empty or not given, port 80 is assumed. Each mcmp_URL MUST
+ have either cmd_path, query or Server-Command header that corresponds to the
+ specific command the manager will fulfil. An example mcmp URL would be:
+
+ http://localhost:8000/manager/info
+ or:
+ http://localhost:8000/manager?info
+ or:
+ GET /manager HTTP/1.0
+ Host: localhost
+ Server-Command: info
+
+ The first example from above allows the web server to enforce command
+ based grained security as shown in the following Apache Httpd example:
+
+ <Location /manager/info>
+ SetHandler cluster-manager
+ Order Deny,Allow
+ Allow from 127.
+ </Location>
+
+ In case the query is not present the manager SHOULD treat the last part
+ of the mcmp_URL as a command in the same fashion as query. Both cmd_path
+ and query are case insensitive.
+
+3.5 Command
+
+ The Command token indicates the command to be performed on the manager
+ identified by the MCMP URL. The command is case-insensitive.
+
+ Command = "INFO" ; Section 3.5.1
+ | "ENABLE" ; Section 3.5.2
+ | "DISABLE" ; Section 3.5.3
+ | "STOP" ; Section 3.5.4
+ | "DELETE" ; Section 3.5.5
+ | "CONFIG" ; Section 3.5.6
+
+ Each command usually carries additional command line parameters. The
+ command line parameters are described for each particular command.
+
+ If the command is not recognised by the manager the manager SHOULD
+ respond with 200 (OK) response and the following entity-body using
+ text/plain MIME-type:
+
+ "?" MCMP-Version CRLF
+
+ Any other non 200 response is treated by the administrator as
+ communication problem between administrator and the manager.
+

+Turk, et. al. Standards Track [Page 7]
+
+RFC 5501 MCMP March 2008
+
+
+
+3.5.1 INFO
+
+ The INFO command causes the manager to gather the information about
+ the specific resource on the server and present that information to
+ the administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ Server-Resource = "Server-Resource" ":"
+ #( resource-type )
+
+ resource-type = ( "*/*"
+ | ( type )
+ | ( type "/" "*" )
+ | ( type "/" subtype )
+ ) *( ";" parameter )
+
+ parameter = token [ "=" ( token | quoted-string ) ]
+
+ type = "server"
+ | "host"
+ | "balancer"
+ | "member"
+ | "application"
+
+ The asterisk "*" character is used to group resource types,
+ with "*/*" indicating all resource types and "type/*" indicating all
+ subtypes of that type. The resource type MAY include resource type
+ parameters that are applicable to that type.
+
+ The example
+
+ Server-Resource: member/*; load-factor; busy
+
+ will return the all members in the server with their load-factor and
+ busy parameter fields. If the parameters are not present then the
+ full information for the resource type SHOULD be returned.
+ The application subtype MAY contain the full application URL
+ in which case the leading slash MUST NOT be provided.
+
+ Server-Resource: application/foo/bar; status; host/*
+
+ will return the list of hosts on which the application with /foo/bar
+ URL is configured, and the status of the application within each host.
+
+
+Turk, et. al. Standards Track [Page 8]
+
+RFC 5501 MCMP March 2008
+
+
+
+ If the manager does contain information about requested type then it
+ MUST respond with 200 (OK) response and the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does contain information about requested subtype then it
+ MUST respond with 200 (OK) response and the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type "/" subtype CRLF
+
+ In case the manager has the requested resource type information then
+ those information is returned as entity-body in random order with each
+ line representing a single resource-type.
+
+ Resource-Response = *( resource-type CRLF )
+
+ The example
+
+ member/node1; load-factor=10; busy=100
+ member/node2; load-factor=10; busy=105
+
+ Administrator MUST take the order of Resource-Response information
+ into account. If the Resource-Response contains the hierarchical
+ information the manager will provide the correct hierarchical order
+ of the resources.
+
+ The example
+
+ host/www.foo.org
+ application/foo; status=200
+ application/bar; status=404
+ host/www.foo.com
+ application/foo; status=503
+ application/baz; status=200
+
+ The resource-type hierarchy is implied by the system and
+ it looks like shown:
+
+ server ---> 1*host ----> 1*application
+ | ^
+ | |
+ +--> balancer --> 1*member -+
+
+ The output of INFO command MUST include the resource type
+ name in case the command evaluation results in multiple resource types
+ returned.
+ The output of INFO command MUST include the parameter name in case
+ the command evaluation results in multiple parameters returned.

+
+3.5.2 ENABLE
+
+ The ENABLE command causes the manager to enable the specific resource
+ on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ If the manager does not contain the requested type object configured
+ then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does not contain the requested subtype object configured
+ then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type "/" subtype CRLF
+
+ In case the manager has the requested resource type object configured
+ and enable succeeds then it MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "OK" CRLF
+
+ In case the enable for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ The error-code is manager specified error code and error-description
+ is human readable description of the error code.
+ Error codes MAY be standard POSIX errno values with corresponding
+ description according to the POSIX specification.
+
+ The example
+
+ ?Error: 22; Invalid argument
+
+ Where 22 corresponds to the EINVAL error code from the POSIX
+ specification.
+ For the resources objects for which the ENABLE command is invalid
+ manager MUST respond with:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+
+ In case the resource object is already enabled the manager MUST
+ reply with the success, and MAY skip any processing that might
+ be needed.

+
+3.5.3 DISABLE
+
+ The DISABLE command causes the manager to disable the specific resource
+ on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ If the manager does not contain the requested type object configured
+ mode then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does not contain the requested subtype object configured
+ mode then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type "/" subtype CRLF
+
+ In case the manager has the requested resource type object configured
+ and disable succeeds then it MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "OK" CRLF
+
+ In case the disable for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ Depending on the resource object type the DISABLE command has different
+ consequences. For node object it MUST disable further acceptance of
+ the request that does not carry the session affinity mark information.
+ This will cause that those nodes MUST get excluded from the balancer
+ scheduler list for all new requests while preserving the ones that carry
+ the session affinity mark.
+ For the resources objects for which the DISABLE command is invalid
+ manager MUST respond with:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+ In case the resource object is already disabled the manager MUST
+ reply with the success, and MAY skip any processing that might
+ be needed.

+
+3.5.4 STOP
+
+ The STOP command causes the manager to stop the specific resource
+ on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ If the manager does not contain the requested type object configured
+ then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does not contain the requested subtype object configured
+ then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type "/" subtype CRLF
+
+ In case the manager has the requested resource type object configured
+ and stop succeeds then it MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "OK" CRLF
+
+ In case the stop for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ Depending on the resource object type the STOP command has different
+ consequences. For node object it MUST stop further acceptance of
+ the request after finishing the currently executing requests.
+ In case there is no more application left attached to this node all
+ the connections from the member to the node MUST be closed.
+ This will cause that those nodes MUST get excluded from the balancer
+ scheduler list for all requests until enabled again.
+ For the resources objects for which the STOP command is invalid
+ manager MUST respond with:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+ In case the resource object is already stopped the manager MUST
+ reply with the success, and MAY skip any processing that might

+3.5.5 DELETE
+
+ The DELETE command causes the manager to remove the specific resource
+ on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ If the manager does not contain the requested type object configured
+ and is in strict mode then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does not contain the requested subtype object configured
+ and is in strict mode then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type "/" subtype CRLF
+
+ In case the manager has the requested resource type object configured
+ and delete succeeds then it MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "OK" CRLF
+
+ In case the delete for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ Depending on the resource object type the DELETE command has different
+ consequences. In general, object resource MUST NOT be deleted in case
+ it is referenced by some other object resource.
+ Application resource object MUST NOT be deleted unless it is in the
+ STOP mode. Node object MUST NOT be deleted if it contains any application
+ that is not in the STOP mode. In both cases the manager MUST respond
+ with the following entity-body using text/plain MIME-type:
+
+ ?Error: 16; Device or resource busy
+
+ Where 16 corresponds to the EBUSY error code from the POSIX
+ specification.
+
+ Deleting static objects or web server objects is not permitted and
+ manager MUST respond with the following entity-body using text/plain
+ MIME-type:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+ Deleting objects from the web server does not mean the server will
+ reuse the memory occupied by the deleted resource, thus the deletion
+ must be taken with care and avoid large number of deletions.

+3.5.6 CONFIG
+
+ The CONFIG command causes the manager to create or update the specific
+ resource on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.
+
+ If the manager does not contain the requested type object configured
+ and is in strict mode then it MUST respond with 200 (OK) response and the
+ following entity-body using text/plain MIME-type:
+
+ "?" "Unknown-Type" ":" type CRLF
+
+ If the manager does not contain the requested subtype object configured
+ then it MUST create the specified object. If the object creation succeeds
+ then it MUST response with the following entity-body using text/plain
+ MIME-type:
+
+ "OK" CRLF
+
+ In case the manager has the requested resource type object configured
+ then CONFIG command MUST update the resource object and MUST overwrite
+ provided parameters. If update of the resource object succeeds then it
+ MUST response with the following entity-body using text/plain MIME-type:
+
+ "OK" CRLF
+
+ In case CONFIG for the specified resource type object is not
+ permitted or the resource or resource parameter is read only,
+ then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+
+
+ In case CONFIG for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ By default, newly created objects MUST be in STOP mode. To be functional
+ the objects MUST be put in the desired operational mode (ENABLE or DISABLE).
+ Creating new objects MAY cause the additional processing on
+ the web server and dependency on the other objects. In case the dependency
+ is not satisfied the manager MUST roll back the creation of the object
+ and it MUST response with the following entity-body using text/plain
+ MIME-type:
+
+ ?Error: 19; No such device
+
+ Where 19 corresponds to the ENODEV error code from the POSIX
+ specification.
+
+3.5.7 EXEC
+
+ The EXEC command is reserved for future use.
+ It will be used for Member to execute the ping/pong or to clear all
+ the active connections or to try to reconnect.
+
+
+3.5.8 RESET
+
+ The RESET command causes the manager to reset the specific resource
+ on the server and presents the result of that operation to the
+ administrator in a form of text/plain MIME-type reply.
+ The Server-Resource header field MUST be present in the request to
+ determine the type of server resource.

+
+ In case the reset for the specified resource type object does not
+ succeeds then the manager MUST response with the following entity-body
+ using text/plain MIME-type:
+
+ "?" "Error" ":" error-code; error-description CRLF
+
+ Depending on the resource object type the RESET command has different
+ consequences.
+ For the resources objects for which the RESET command is invalid
+ manager MUST respond with:

+4 Resource Types
+
+ Resource types are fixed objects or object collections inside web server
+ accessible by manager. There are five basic resource types; server, host,
+ balancer, member and application (see section 3.5.1).
+ Each resource type MAY contain the collection of name based resources
+ either as resource instance or reference to the resource instance.
+ In case the object is a reference to the resource instance the
+ resource collection item MAY contain local resource parameters. The object
+ reference MUST inherit parameters from the object instance, but then if
+ the object have local parameters they MUST preserve local data integrity.
+ Updating instance parameters MAY propagate the values to all references
+ local data having the same parameter.
+
+4.1 Server
+
+ Server resource type is the root object in the system and contains the
+ web server parameters. It MUST support the INFO command and MAY support
+ the CONFIG command. In case the CONFIG is not supported the manager MUST
+ respond with EPERM error code (see section 3.5.6).
+
+4.1.1 General Information
+
+ Server MUST provide the following parameters:
+
+ ServerName
+ Hostname and port that the server uses to identify itself.
+
+ ServerRoot
+ Base directory for the server installation.
+
+ ServerVersion

+
+ ServerBuilt
+ Date and time when the server was built.
+
+ ServerArchitecture.
+ CPU architecture of the server (32 or 64 bit).
+
+ ThreadsPerChild
+ Number of threads created by each child process.
+ If the server does not use threading model then it MUST
+ report this value as 1.
+
+ MaxRequestsPerChild
+ Limit on the number of requests that an individual child server
+ will handle during its life. After MaxRequestsPerChild requests,
+ the child process will die.

+ current-configuration = *( "File" ":" configuration-file CRLF
+ *( [line-number] ":" directive CRLF )
+ )
+
+ The CurrentConfiguration parameter MUST be the only parameter

+ Host resource type represents the servers Host or Virtual Host.
+ Host MAY contain any number of application resource objects.
+ By default the Host object is created from server native configuration.
+
+ The Host that was created from server native configuration
+ MUST not be deleted. If the manager tries to DELETE such Host
+ the manager must respond with the following entity-body using
+ text/plain MIME-type:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+
+
+4.2.1 General Information
+
+ Host MUST provide the following parameters:
+
+ ServerName
+ Specifies what hostname must appear in the request's Host: header
+ to match this virtual host.
+
+ ServerAlias
+ Alternate names for a host used when matching requests
+ to name-virtual hosts.
+ [ "ServerAlias" "=" ] *( hostname SP )
+
+ IsVirtual
+ Is this a virtual host.
+ [ "IsVirtual" "=" ] ( "On" | "Off" )
+
+ DocumentRoot
+ Directory that forms the main document tree visible from the web.
+
+ ServerPath
+ Legacy URL pathname for a name-based virtual host that is accessed
+ by an incompatible browser.
+
+ KeepAlive
+ This server supports the persistent connections.
+ [ "KeepAlive" "=" ] ( "On" | "Off")
+
+ KeepAliveTimeout
+ Amount of time the server will wait for subsequent requests on a
+ persistent connection.
+
+ MaxKeepAliveRequests
+ Number of requests allowed on a persistent connection.
+
+ TimeOut
+ Amount of time the server will wait for certain events before
+ failing a request

+
+
+
+ LimitRequestBody
+ Specifies the number of bytes from 0 (meaning unlimited) to
+ 2147483647 (2GB) that are allowed in a request body.
+
+ Address
+ The bound IPV4 or IPV6 address for this host.
+
+ Port
+ The bound port for this host.
+
+ The host MAY provide the following parameters:
+
+ VirtualName
+ The name given in <VirtualHost > configuration.
+
+4.2.2 Application
+
+ Application resource type is configurable object inside host,
+ and it maps the incoming URLs to global balancer object.
+ Host MUST support unlimited number of application resource objects
+ and MUST support all commands.
+ If the application was already configured and created inside balancer
+ resource object then the manager MUST create application object
+ instance inside host object, otherwise it MUST reference already
+ created application instance inside balancer object.
+ This allows to have multiple instances of the application that have
+ the same name. Likewise it allows to share the common applications
+ between host resource objects.
+
+ Each application configured inside host MUST have it's own status
+ parameter that defines how the manager will map the application.
+
+ application-status = "Status" "="
+ ( 200 ; Application mapping allowed
+ | HTTP-Status ; Return HTTP-Status to the client
+ )
+
+ HTTP-Status as defined in RFC2068 [10].
+
+ When configuring the application object application-status MUST be
+ set to 200 unless explicitly specified inside CONFIG command.
+ On evaluation if the application is reference the manager MUST
+ first use the application-status from the instance of the application
+ object and only if the application-status is 200 the manager MAY
+ apply his local application-status.
+
+ DELETE command MUST remove the application object from the host.
+ In case the application object was a reference then the manager MUST
+ preserve the original application object and delete only the local
+ parameter data. Deleting the application from the host is the same
+
+
+
+Turk, et. al. Standards Track [Page 19]
+
+RFC 5501 MCMP March 2008
+
+
+
+ as setting the application-status to 404, so the administrator
+ MAY use this instead object deletion. Processing application with
+ application-status equal to 404 MUST produce the same result as if
+ the application was not defined at all.
+
+ STOP command MUST set the application-status to 404.
+ DISABLE command MUST set the application-status to 503.
+ ENABLE command MUST set the application-status to 200.
+ Those commands are convenience methods for using the CONFIG
+ command with corresponding application-status value.
+
+ The example
+
+ DISABLE Server-Resource: host/www.foo.org; application/*
+
+ MUST set the application-status to 503 for all the applications
+ inside www.foo.org host resource object. Next client request to the
+ www.foo.org host MUST then always return 503 HTTP-Status message
+ to the client for all configured applications.
+
+ The following example does exactly the same thing as above, but
+ using the CONFIG command and status parameter to set the
+ application-status.
+
+ CONFIG Server-Resource: host/www.foo.org; application/*; status=503

+
+4.3 Balancer
+
+ Balancer resource type is static object inside server. Default
+ balancer object instance MUST be created at server startup and
+ present for the server lifetime. The name of this resource MUST
+ be set to "_default_", and server MUST use this balancer if the
+ balancer resource name or type was not provided with the command.
+
+ Balancer object instance contains the list of member instance
+ objects and it MUST support all commands.
+
+ Additional balancer object instances MAY be created inside server
+ and the server SHOULD NOT limit their number. However different
+ balancer object instances cannot share the same member object
+ instances and server MUST assure that two members with the same
+ member-host and member-port do not appear in two different balancer
+ instances. In case such attempt is made the manager must respond
+ with the following entity-body using text/plain MIME-type:
+
+ ?Error: 18; Cross-device link
+
+ Where 18 corresponds to the EXDEV error code from the POSIX
+ specification.
+
+
+4.3.1 StickySession
+
+ StickySession is balancer parameter with default value set to "On".
+ The balancer MAY extract the data from the sticky-session-cookie
+ or from the sticky-session-path to maintain the session affinity
+ for the particular member matching the session-route
+ (see 4.3.1 and 4.3.2).
+
+
+4.3.2 StickySessionCookie
+
+ StickySessionCookie is balancer parameter with default value
+ equal to "JSESSIONID" and is used to find the session affinity
+ mark that matches the member name. The member name comparison
+ MUST be case insensitive. However the comparison for the
+ StickySessionCookie MUST be case sensitive.
+
+ If the Cookie or Cookie2 header value provided by the client have
+ multiple occurrences of the StickySessionCookie only the last one
+ MUST be used for further processing.
+
+ sticky-session-cookie = "StickySessionCookie" "=" string
+
+
+
+
+Turk, et. al. Standards Track [Page 21]
+
+RFC 5501 MCMP March 2008
+
+
+
+ The extracted route information from the Cookie is
+
+ sticky-route = StickySessionCookie" "="
+ #( session-route )
+
+ session-route = ( session-id [ "." [ token ] ] )
+
+ session-domain = ( session-route
+ | session-route [ "." token ] ]
+ )
+
+ If the session-id contains the "." character everything after
+ that character MUST be treated as session-route. If the session
+ route contains "." character everything after that character
+ MUST be treated as session-domain.
+
+
+4.3.3 StickySessionPath
+
+ StickySessionPath is balancer parameter with default value
+ equal to ";jsessionid" and is used to find the session affinity
+ mark that matches the member name. The member name comparison
+ MUST be case insensitive. However the comparison for the
+ StickySessionPath MUST be case sensitive.
+
+ If the URL header value provided by the client have
+ multiple occurrences of the StickySessionPath only the last one
+ MUST be used for further processing.
+
+ sticky-session-path = "StickySessionPath" "=" string
+
+ The extracted route information from the Cookie is
+
+ sticky-route = "StickySessionPath" "="
+ #( session-route )
+
+ session-route = ( session-id [ "." [ token ] ] )
+
+ session-domain = ( session-route
+ | session-route [ "." token ] ]
+ )
+
+ If the session-id contains the "." character everything after
+ that character MUST be treated as session-route. If the session
+ route contains "." character everything after that character
+ MUST be treated as session-domain.

+
+
+4.3.4 StickySessionRemove
+
+ StickySessionRemove is balancer parameter with default value
+ equal to "On" and is used to remove the sticky-session-cookie or
+ the sticky-session-path for failed mappings and routes.
+ (see section 4.3.5).
+
+ [ "StickySessionRemove" "=" ] ( "On" | "Off" )
+
+ When set to "On" the server MUST remove the sticky-session-cookie
+ from the Cookie header or sticky-session-path from the URL.
+
+
+4.3.5 StickySessionForce
+
+ Specifies whether requests with session-route for members that are
+ in error state should be rejected. If StickySessionForce is set to
+ "On" and the member that matches that session-route is in error state,
+ client will receive 500 (Server Error).
+ If set to "Off" (default value) failover on another member will be
+ issued with possibility of loosing client session.
+
+ [ "StickySessionForce" "=" ] ( "On" | "Off" )
+
+ If StickySessionRemove was set to "On" and member that matches the
+ session-route was in error state, the server MUST remove the
+ sticky-session-cookie from the Cookie header or sticky-session-path
+ from the URL. However this directive MUST be evaluated only if
+ the StickySession was set to "On"
+
+ For domain session routes all members of the domain MUST be
+ in error state to evaluate this rule.
+
+
+4.3.6 TimeOut
+
+ Connection wait timeout in seconds. If not set the balancer will
+ wait until the free connection is available. This directive is
+ used for limiting the number of connections to the node together
+ with MaxConnections member parameter.
+ Default value is server TimeOut.

+ communication to the node.
+
+ type = "Type" "="
+ #( protocol-type )
+
+ protocol-type = "ajp"

+ | "https"
+
+ Once created the member MUST NOT change its protocol-type. Any such
+ attempt MUST respond with the following entity-body using
+ text/plain MIME-type:
+
+ ?Error: 1; Operation not permitted
+
+ Where 1 corresponds to the EPERM error code from the POSIX
+ specification.
+
+
+4.4.2 Address
+
+ Host name or IP address of the node to which the member connects.
+ The Host name can have a port number embedded separated by the
+ colon (":") character. Default value for the Address is "localhost"
+
+ Once created the member MUST NOT change its address unless the
+ member is in the STOP mode. Any such attempt must respond with
+ error message (see section 4.4.1).
+
+
+4.4.3 Port
+
+ Port number of the node to which the member connects.
+ The default value depends on the protocol-type and is
+
+ ajp = "8009"
+ http = "8080"
+ https = "8443"
+
+ Once created the member MUST NOT change its address unless the
+ member is in the STOP mode. Any such attempt must respond with
+ error message (see section 4.4.1).

+
+
+4.4.4 Route
+
+ Route of the member is a value that SHOULD match to the session-route.
+ Balancer to whom the member belongs will select this member if the
+ session-route matches the Route. Route value MUST be case insensitive.
+
+ The length of the Route MUST be within 0 and 63 characters. In case
+ the length of Route is outside the limited range the manager MUST
+ respond with the following entity-body using text/plain MIME-type:
+
+ ?Error: 22; Invalid argument
+
+ Where 22 corresponds to the EINVAL error code from the POSIX
+ specification.
+
+
+4.4.5 Domain
+
+ Domain of the member is a value that SHOULD match to the session-domain.
+ Balancer to whom the member belongs will select this member if the
+ session-domain matches the Domain. Domain value MUST be case insensitive.
+ Balancer MUST match the Domain only if the matched session-route member
+ is not inside operational state.
+
+ The length of the Route MUST be within 0 and 63 characters. In case
+ the length of Domain is outside the limited range the manager MUST
+ respond with EINVAL error code (see section 4.4.4).
+
+
+4.4.6 Ping
+
+ Ping property MAY cause member to send a CPING request on ajp connection
+ before forwarding a request. The parameter is the delay in seconds
+ to wait for the CPONG reply. Currently this has an effect only if the
+ member Type is ajp. If the value of the property is zero (default)
+ then the member MUST NOT send the CPING requests.
+
+ If the attempt is made to set the non zero value to the member which
+ Type is different then ajp the manager MUST respond with EINVAL
+ error code (see section 4.4.4).

+
+ Maximum number of connections that are allowed at any moment to
+ the node on each child process inside server. For threaded servers
+ this value MUST be within the range of 1 and the number of
+ ThreadsPerChild (see section 4.1.1). For non threaded servers this
+ value MUST always be one.
+
+ In case MaxConnections is outside the limited range the manager MUST
+ respond with EINVAL error code (see section 4.4.4).
+
+
+4.4.8 MinConnections
+
+ Minimum number of connections that the member will keep opened.

+4.4.10 LF
+
+ Load Factor is the property of the member used by the balancer
+ to schedule the load. The value of LF property MUST be
+ within the 1 and 100 and defines the normalized weighted load
+ applied to the member. Default value is 1.
+
+
+4.4.11 Distance
+
+ An integer number to express preferences between the balanced
+ members of an balancer. A balancer MUST never choose some
+ member in case there is another usable member with lower distance.
+
+ Only in case all members below a given distance are in error,
+ disabled or stopped, member of a larger distance MAY be eligible
+ for balancing. This property is used for creating hot standby
+ members. Multiple hot standby chains might be created each
+ having the same Distance property larger by one.
+ Default value for Distance property is zero.
