Re: mod_jk sticky session still not working
P.S. I see a mention of "cluster" in the documentation for jvmRoute. Do I need to configure a "cluster" perhaps? -- Scott.

That sounds very reasonable, and I modifed the two server.xml Engine elements as suggested, but it appears to make no difference. Below are 3 segments from mod_jk.log. The first segment shows the initial request coming in without a sessionid. The request is routed to tomcat1 with route=tomcat1. The second segment shows the response coming back from tomcat1, with a new session id. The third segment shows the second request coming in with the expected session id, and shows tomcat2 being selected with route=tomcat2. You say I don't have session affinity mark. How would that show up in the log? Is the "partial sessionid" an indication of the problem? -- Scott.

Re: mod_jk sticky session still not working
Hi Mladen, I really appreciate your help, and am happy that you're seeing a problem in the log output. I think I've got the Engine attributes specified correctly, and the two different jvmRoute values do show up in the mod_jk log. jvmRoute="tomcat1" /> jvmRoute="tomcat2" /> Maybe if I give the Engines different names? It sounds like we're expecting the jvmRoute to be appended to the sessionId that is returned in the Set-Cookie header? If so, I guess mod_jk is working as expected, and I'm just not getting the right sessionid created by Tomcat. I'm not using Boss. Just Apache and Tomcat on a single Solaris machine. -- Scott.
