mod_cluster is not maintaining sticky sessions

Solution Verified - Updated -


  • Sticky sessions are not working with mod_cluster
  • We've configured 2 Red Hat JBoss EAP' 5.2.0s in two different servers. We are using mod-cluster for load balancing. Now it is observed that the web server is directing the request to both EAPs and session stickiness is getting lost.
  • Retrieving something from the HTTP session results in a NullPointerException.
