Hi, I am having a quite serious problem for which I could not find solution. Tried to ask this question on couple apache forum and was adviced to ask it on tomcat forums.
The configuration: Apache: 2.2 serving as load balancer workers.properties worker.list=balancer worker.engine1.port=10001 worker.engine1.host=localhost worker.engine1.type=ajp13 worker.engine1.lbfactor=1 #worker.engine2.port=10002 #worker.engine2.host=localhost #worker.engine2.type=ajp13 #worker.engine2.lbfactor=1 #worker.engine3.port=10003 #worker.engine3.host=localhost #worker.engine3.type=ajp13 #worker.engine3.lbfactor=1 worker.balancer.type=lb worker.balancer.sticky_session=1 worker.balancer.sticky_session_force=1 worker.balancer.balance_workers=engine1,engine2,engine3 3 Tomcat 6 instances with ajp connector with two webapps without session serialization e.g. <Connector port="10001" redirectPort="10011" connectionTimeout="-1" protocol="AJP/1.3"> </Connector> <Context path="/webapp1" distributable="false"> </Context> <Context path="/webapp2" distributable="false"> </Context> Also it's setup as cluster with Clustered SSO Valve: <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/> <Valve className="org.apache.catalina.ha.authenticator.ClusterSingleSignOn"/> The problem is that once user logs in into webapp1 and goes to link to webapp2, it's not guarantied that he will go to same box as webapp 1. This results in session lost and sometimes Principal is not correctly propagated between webapp1/webapp2 (). Using session serialization is not an option because sessions used in webapp1/webapp2 are very heavy and it results in awfull performance. Is there a way to force apache to always rebalance to same box for different tomcat contexts?
