mod_cluster does not maintain session stickiness when multiple balancers are used

Solution Verified - Updated -

Issue

  • We have multiple JBoss clusters behind our httpd/mod_cluster load balancer. Each JBoss cluster is configured with a different mod_cluster balancer name. mod_cluster is not maintaining session affinity when these multiple balancers are used at once.

Environment

  • JBoss Enterprise Application Platform (EAP)
    • 5.2.0
    • 6.0.0
  • JBoss Enterprise Web Server (EWS)
  • Apache httpd
  • mod_cluster
    • 1.0.10.GA_CP04 and earlier
    • 1.2.1.Final and earlier
