Aaron Ogburn commented on MODCLUSTER-443:
-----------------------------------------

I'm able to reproduce the customer issue consistently with the latest versions.  Extra debug logs were showing that find_node_context_host includes the ;jsessionid in the context that it searches for on the balancer:
{code}
[Mon Nov 17 15:40:01 2014] [debug] mod_proxy_cluster.c(2948): proxy_cluster_trans for 0 (null) (null) uri: /helloworld;jsessionid=blablabla args: (null) unparsed_uri: /helloworld;jsessionid=blablabla
[Mon Nov 17 15:40:01 2014] [debug] mod_proxy_cluster.c(2769): cluster: balancer://mycluster Found value blablabla for stickysession JSESSIONID|jsessionid
[Mon Nov 17 15:40:01 2014] [debug] mod_proxy_cluster.c(2769): cluster: balancer://mycluster Found value blablabla for stickysession JSESSIONID|jsessionid
[Mon Nov 17 15:40:01 2014] [debug] mod_proxy_cluster.c(1943): find_node_context_host: /helloworld;jsessionid=blablabla node: 1 vhost: 1 context: /helloworld
[Mon Nov 17 15:40:01 2014] [debug] mod_proxy_cluster.c(3012): proxy_cluster_trans DECLINED (null) uri: (null) unparsed_uri: /helloworld;jsessionid=blablabla
[Mon Nov 17 15:40:01 2014] [error] [client 127.0.0.1] File does not exist: /apache/htdocs/helloworld;jsessionid=blablabla
[Mon Nov 17 15:40:03 2014] [debug] mod_manager.c(1907): manager_trans STATUS (/)
{code}

So we can't even get a "/context;jsessionid=..." request to proxy from httpd to JBoss through mod_cluster.  Session data and servlet mappings don't enter the equation.

> This is similar to MODCLUSTER-328, but in regards to ; instead of ?. 
> mod_cluster does not recognize ; as a delimiter when checking the request context. Thus with no trailing slash on index page requests, it treats ;jsessionid as part of the request context and tries to check the balancer for a deployed context of /helloworld;jsessionid=..., which doesn't exist and 404s. Adding the trailing slash, mod_cluster can properly delimit this and then sees the context (so /helloworld/;jsessionid=... works just fine).
