Clustered HTTP session problem

[chris_katz]

I've set up a 2 node cluster using JBoss 4.0.2.
Apache2 with mod_jk is used as a load balancer with sticky sessions set to true.
The clients of my application would be web browsers, Java and other(non-Java) clients -- some of them not supporting session cookies. I've set to "false" the cookies attribute in Tomcat's context.xml and implemented the app. to use URL rewriting.

There is a particular problem: session IDs generated from one server have a suffix ".node1", while from the other - don't.
The first node seems to be a kind of "preferred" node by Apache(although there is on "local_worker_only" set in worker.properties). When accessing the application from a web browser a new HTTP session is established only when accessing the node with suffixed session IDs. Attempts to establish a session to the other node are unsuccessful.

UseJK attrib. is set to "true" in both server's jboss-service.xml

I won't post any config files at this stage.
Any help/hint will be appreciated!

1. You can make sure that your setup is working correctly by runnign with "sticky" session with web access only.

2. Upgrade to 4.0.3. I remember I have fixed the mod_jk fail over problem in later release (not sure exactly which one though).

Hi,

Thank you for the feedback. The clustered config. is functioning quite fine. It turned out(after comparing the 2 nodes' config. files) that the problem was caused by misspelled attribute "jvmRoute"...and obviously there were no session ID sufixes generated from that node.

Anyway, I will follow your advice and upgrade to 4.0.3

thanks again!
