mod_proxy: sticky session does not work - apache

Question

I have two JBoss AS 7 servers and I'm doing load balancing using mod_proxy. Almost everything works fine besides sticky sessions. I have session id in a cookie not in the URL as JSESSIONID.
Here is my apache configuration:
NameVirtualHost *:80
<VirtualHost *:80>
ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid nofailover=Off
ProxyPassReverse / balancer://tutcluster/
ProxyPassReverse / http://server1:8080/
ProxyPassReverse / http://server2:8080/
ProxyPreserveHost On
ProxyRequests Off
<Location / >
Order deny,allow
Allow from All
</Location>
<Proxy balancer://mycluster/>
BalancerMember http://server1:8080 route=jbossWeb1 retry=60
BalancerMember http://server2:8080 route=jbossWeb2 retry=60
</Proxy>
</VirtualHost>

Answer 1

OK, I've found it. There were two problems Firstly I forgot to set jvmRoute property in the JBoss configuration. So I set:
<system-properties>
<property name="jvmRoute" value="nodeX"/>
</system-properties>
and changed workers configuration to:
BalancerMember http://server1:8080 route=nodeX retry=60
The second problem was nofailover=Off. It probably caused that some parts of the static content was loaded from one server and some parts of it -- from another one.
