I have two physical servers running Tomcat 7.0.42, each running the same webapp.
I'm interested in some advice with session replication. I'm not concerned with fail-over, or high-availability. I just want to be able to have sessions maintained when the user is routed to a different server by the load balancer. Is the documentation accurate in that just doing: *Simply add <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/> to your <Engine> or your <Host> element to enable clustering.* I've been through the docs and still a little confused as to the best way to implement session replication. TIA Alec
