I have two servers jboss 4.0.4.GA in cluster. The web server is apache Apache/2.0.52 which is using module mod_jk/1.2.25 to load_balancing and failover. The OS is RHEL AS 4.5. All this system run very well.

I'm trying to migrate this old system to a newer one. The new cluster has two nodes jboss 4.0.4.GA, but the OS is RHEL 5.3 and web server Apache/2.2.3 which is using modules proxy_module,proxy_ajp_module,proxy_balancer_module instead of mod_jk.

I can't reproduce the behaviour of mod_jk with mod_proxy.
In old system I have the next config files:

/etc/httpd/conf/workers.properties
worker.list=loadbalancer,status
worker.nodo1.port=8009
worker.nodo1.host=localhost
worker.nodo1.type=ajp13
worker.nodo1.lbfactor=10
worker.nodo2.port=8009
worker.nodo2.host= 10.10.1.158
worker.nodo2.type=ajp13
worker.nodo2.lbfactor=30
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=nodo1,nodo2
worker.loadbalancer.sticky_session=1
worker.status.type=status

/etc/httpd/conf/uriworkermap.properties
/jmx-console=loadbalancer
/jmx-console/*=loadbalancer
/web-console=loadbalancer
/web-console/*=loadbalancer
/*.jsp=loadbalancer
/*.do=loadbalancer
/*.asp=loadbalancer
/services/*=loadbalancer
/servlet/*=loadbalancer
/index.html=loadbalancer
/promo/*=loadbalancer
/sanvalentin=loadbalancer
/sanvalentin/*=loadbalancer
/JSON-RPC*=loadbalancer

With this configuration the static contents was served by apache y the dynamic contents are served by JBoss (*.jsp, *.do, *.asp, etc). Both contents could be in the same directories. For this reason I used /*.do, /*.asp, /*.jsp in uriworkermap.properties.

In other hand the configuration of mod_proxy is:

-----

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

<Proxy balancer://mycluster>
Order deny,allow
Allow from all

BalancerMember ajp://nodeA:8009 route=nodo1 retry=60 loadfactor=10
BalancerMember ajp://nodeB:8009 route=nodo2 retry=60 loadfactor=10


<Location / >
Allow From All
ProxyPass balancer://mycluster/ stickysession=JSESSIONID nofailover=on lbmethod=byrequests
ProxyPassReverse balancer://mycluster/


<Location /balancer>
SetHandler balancer-manager

Order Deny,Allow
Deny from all
Allow from 192.100.30.161


ProxyStatus On

-------------------

With this configuration all the contents are served by jboss nodes.

If I change the <Location / > in order to use the form <Location /*.jsp > or similar it doesn't forward the calls to the JBoss. I want to achieve the same behaviour that I achieved with uriworkermap.properties.

In Addition I think the stickysession is not running. I've made a jsp (whoami.jsp) who tell me what's the node which is serving the page. I've detected the next behaviour:

From a Browser I request the page whoami.jsp and when the response is given by the server A, If I refresh this page the next times, I get the response from server B. Why is not served by the server A?

Do you know what is happening and how could i get the same behaviour like the mod_jk?

Thanks in advance
