> Now that we properly show all the individual virtual hosts for a node, mod_cluster-manager may display a messy page with the aliases from a single Virtual Host broken up with multiple instances of the Virtual Host and its contexts.  This can occur with our concurrent start ups now when JBoss has multiple applications bound to virtual servers that are deploying and enabling at once.  The dump output demonstrates the cause:
> balancer: [1] Name: mycluster Sticky: 1 [JSESSIONID]/[jsessionid] remove: 0 force: 0 Timeout: 0 maxAttempts: 1
> node: [1:1],Balancer: mycluster,JVMRoute: 4e6189af-0502-3305-8ff3-fad7fee8b516,LBGroup: [],Host: 127.0.0.1,Port: 8009,Type: ajp,flushpackets: 0,flushwait: 10,ping: 10,smax: 1,ttl: 60,timeout: 0

> host: 11 [example8.com] vhost: 2 node: 1
> host: 12 [example7.com] vhost: 2 node: 1
> host: 13 [testhost3] vhost: 2 node: 1
> context: 1 [/helloworld2] vhost: 3 node: 1 status: 1
> context: 2 [/helloworld3] vhost: 1 node: 1 status: 1
> context: 3 [/] vhost: 2 node: 1 status: 1
> The messy html representative of this bad output is attached.  Note host entry 9 is for vhost 3, but separated in the html from the other vhost 3 entries.
> The problem is in manager_info_hosts.  It assumes all of those entries will be in order, printing out the Virtual Host/Context lines whenever a different vhost entry is seen.  It'd be much cleaner if we ensured each VirtualHost was only ever printed once on the page.
