Thanks for everyone's response! Finally I figured out that the problem was caused by naming inconsistency between workers.properties and the jvmRoute value in server.xml. The jvmRoute under the engine tag in server.xml has to be defined with the same name as the worker name for the same tomcat instance.
BTW, in the latest version of mod_jk, the property name balanced_workers has been changed to balance_workers.

Here's a snippit from our workers.properties. worker.list=lbcon # ww1 worker.ww1.port=8009 worker.ww1.host=192.168.X.Y worker.ww1.type=ajp13 worker.ww1.lbfactor=1 worker.ww1.cachesize=20 worker.ww1.local_worker=0 # ww2 worker.ww2.port=8009 worker.ww2.host=192.168.X.Z worker.ww2.type=ajp13 worker.ww2.lbfactor=1 worker.ww2.cachesize=20 worker.ww2.local_worker=1 worker.lbcon.type=lb worker.lbcon.sticky_session=1 worker.lbcon.balanced_workers=ww1,ww2 worker.lbcon.local_worker_only=0 John -----Original Message----- From: Duan, Nick [mailto:[EMAIL PROTECTED] Sent: Thursday, November 17, 2005 11:02 AM To: tomcat-user@jakarta.apache.org Subject: Session not sticky in 5.5 with load balancer I am running an Apache httpd server as the load balancer with two tomcat instances.
