Using mod_jk, if one node goes down the others pick-up the slack. I have much less experience with mod_proxy_*. > Also, is there any way to detect which Tomcat is being used by the user > right now? On which end? You want to check from the client end? If you look at the session id, it will have the jvmroute in it, appended onto the end. Your session id will be something like "37680235094857.node1". > Here are the changes I made : > > For apache2 in sites-enabled/000-default : > > > <Proxy balancer://mycluster> > BalancerMember ajp://localhost:8010 route=jvmroute-first > connectiontimeout=10 > BalancerMember http://localhost:8011 route=jvmroute-second > connectiontimeout=10 Why are you using AJP for one connection and HTTP for the other?
