I haven't used JK2, but I know how this works with JK(1) and I think it's more or less the same thing. Some configuration has to be done in JK2, and other configuration has to be done in the tomcat instances that are being balanced. The way that sticky sessions work is that the JSESSIONID cookie value provided by Tomcat includes an indicator of which Tomcat instance set the cookie. The JK (or JK2) connector looks at this indicator to decide which instance should handle new requests. That's pretty simple, right? In JK2, according to the documentation, there is a "tomcatId" attribute for channel.socket configuration stanzas. This attribute is automatically set to the local name part of the channel.socket name. So suppose you have a socket channel going to a tomcat instance on host flubber.foo.com, port 8080. You name the channel: channel.socket:flubber.foo.com:8080 And the tomcatId gets set to flubber.foo.com:8080 unless you change that explicitly. This is the JK2 part of the sticky session configuration. Now you go to the server.xml configuration file for the tomcat running on flubber.foo.com, port 8080. In the Engine element, you set the attribute jvmRoute to "flubber.foo.com:8080". When that Tomcat instance sets a JSESSIONID cookie, the value will be something like: 0928DE35C1F410D99ABDD4E7A6FA65F6.flubber.foo.com:8080 Now when the next request comes in from that browser this JSESSIONID cookie value will be sent in the request. JK2 will look at the flubber.foo.com:8080 part of the value, realize that it needs to send the request through that channel, and voila, server affinity just like magic! Does that make sense? It might help other people with the same problem if you report back whether this works or not. Like I said, I haven't used JK2 so I don't know for sure.
