Correctly shutting down a websocket handler
by Robin Anil
When a client disconnects, I see that onClose is not being fired. The only
way this seems to be firing if client sents a close frame.
Is there any way to detect disconnection and immediately close all the
opened resources.

Worker thread queue size and timeout behavior
by Brad Wood
I'm looking for a bit of understanding on just how Undertow handles large
numbers of requests coming into a server. Specifically when more requests
are being sent in than are being completed. I've been doing some load
testing on a CFML app (Lucee Server) where I happen to have my io-threads
set to 4 and my worker-threads set to 150. I'm using a monitoring tool
(FusionReactor) that shows me the number of currently executing threads at
my app and under heavy load I see exact 150 running HTTP …
[View More]threads in my app
server, which makes sense since I have 150 worker threads. I'm assuming
here that I can't simultaneously process more requests than I have worker
threads (please correct if I'm off there)
So assuming I'm thinking that through correctly, what happens to additional
requests that are coming into the server at that point? I assume they are
being queued somewhere, but
- What is this queue?
- How do I monitor it?
- How big can it get?
- Where do I change the size?
- How long do things stay in there before sending back an error to the
HTTP client?
- Can I control what error comes back to the HTTP client in that
scenario?
- If I'm using an HTTP/S and AJP listener, do they all share the same
settings? Do they share the same queues?
I've done a bit of Googling and reviewed some docs but haven't quite found
any definitive information on this, and a lot of info I found was about
Wildfly specifically so I wasn't sure how much of it applied.
Thanks!

LoadBalancingProxyClient URI mapping
by paroczizs .
Hi undertow Dev!
I would like to use the LoadBalancingProxyClient from a custom handler and
forward the request to a different server and different URI.
The server is set up this way:
LoadBalancingProxyClient lb = ..
lb.addHost(new URI("http://localhost:5001/other-app/service1"));
The handler is mapped like this
path = /my-server/serv-one
In the log I found this:
DEBUG [io.undertow.server.handlers.proxy] (default I/O-2) Sending request
ClientRequest{path='/other-app/service1/my-server/…
[View More]serv-one', method=GET,
protocol=HTTP/1.1} ..

Wildfly 11 + ReverseProxy + 2 was ssl
by paroczizs .
Hi UndertowDev,
Is it possible to configure 2 way ssl with reverse proxy in wildfly
standalone.xml?
The schema and the realm set properly in case of 1 way ssl works fine
however when the back end requests for the client cert the wildfly does not
sent it:
22:12:41,187 INFO [stdout] (default task-2) *** CertificateRequest
...
22:12:41,213 INFO [stdout] (default task-2) Warning: no suitable
certificate found - continuing without client authentication
realm looks like this:
<security-…
[View More]realm name="PserverRealm">
<server-identities>
<ssl>
<keystore path="/home/config/pserver.jks"
keystore-password="123456" alias="pserver" key-password="123456"/>
</ssl>
</server-identities>
<authentication>
<truststore path="/home/config/pserver.jks"
keystore-password="123456"/>
</authentication>
</security-realm>
Another question whether is basic authentication possible from the
configuration?
Thank you in advance, Zsolt

Serving files in a different hierarchy than the one in the file system
by Johannes Ernst
I’m attempting to serve a bunch of static files, which exist in the file system, but in various directories that do not correspond to the URL namespace. Example:
http://example.com/foo/one => /var/lib/one/bar
http://example.com/foo/two => /var/lib/two/bar
I have the mapping from incoming request URL to File to be served in a Map<String,File>. Now I’m attempting to hook up Undertow so it can serve those files according to my mapping, and I’m not entirely sure where to best plug …
[View More]this in without having to write loads of code.
As far as I can tell, I would need to implement my version of ResourceManager and Resource, sort of like File/PathResource/Manager, but there’s a lot of code there, not all of which I understand, and it would perhaps turn into a maintenance nightmare on my end.
I cannot see a straightforward way of overriding those classes either to “slide in” an alternate mapping.
Is there a better way of doing this?
Thanks,
Johannes.

Path variables
by Fernando Cruz
Hi,
I define two template paths with the following implementation:
public class UndertowTwoPathVariablesApplication {
private static final Logger LOGGER = LoggerFactory.getLogger(UndertowTwoPathVariablesApplication.class);
public static void main(final String[] args) {
Undertow.builder()
.addHttpListener(8080, "localhost")
.setHandler(
Handlers.routing()
.get("/api/v1/orders/{orderId}/items/", (exchange) -> {
LOGGER.info("The …
[View More]path template defined is '/api/v1/orders/{orderId}/items/'");
LOGGER.info("The request URI '{}'", exchange.getRequestURI());
exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
exchange.setStatusCode(StatusCodes.OK)
.getResponseSender().send("Retrieve all Items of the Order '"
+ exchange.getQueryParameters().get("orderId").getLast() + "'");
})
.get("/api/v1/orders/{orderId}/items/{itemId}", (exchange) -> {
LOGGER.info("The path template defined is '/api/v1/orders/{orderId}/items/{itemId}'");
LOGGER.info("The request URI '{}'", exchange.getRequestURI());
exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
exchange.setStatusCode(StatusCodes.OK)
.getResponseSender().send(
"Retrieve the Item '" + exchange.getQueryParameters().get("itemId").getLast()
+ "' of the Order '" + exchange.getQueryParameters().get("orderId").getLast() + "'");
}))
.build()
.start();
}
}
And using the version 2.0.0.Beta1 of undertow-core I can not enter to the first Handler defined.

This not happen when the path have just one path variable. I create the repo https://github.com/b0gg4rd/undertow-path-variable with the two implementations.
