Hi All,
I'm trying to setup session clustering between two Tomcat 6.0.13
instances with Apache 2.2 and Mod JK 1.2.23.
The problem I'm having is that every request returns me a new session
so the users state is not kept, So i assume that the clustering is not
configured correctly.
Looking at the manager app on both tomcats i see the same number of
sessions, so they seem tobe replicated between the server.
Can anyone help me out please.
Here is my server.xml from tomcat 1
