Dear List, I am having a Tomcat7 cluster of in-memory session replication.
Tomcat-A - 192.168.1.100 Tomcat-B - 192.168.1.101 I have simple application which does the login before navigating to the pages. I have apache configured with mod_jk to handle sticky sessions. when I am accessing the url , http://www.example.com the session is getting established in one of the Tomcat server, suppose it established in Tomcat-B. I starts navigating the pages after login. Now I stopped Tomcat-B, in this can my session continues in Tomcat-A & it's doesn't ask me for relogin to upon clicking in any links. Problem starts when I try to starts Tomcat-B, when it's completely starts & try to navigating any link on the same session , it's starts asking for relogin. Tomcat-B --> Tomcat-A , Tomcat-B Stops , no relogin. Tomcat-B starts , relogin Tomcat-A --> Tomcat-B , Tomcat-A Stops , no relogin. Tomcat-A starts , relogin Below is my server.xml, context.xml, web.xml, workers.properties & httpd.conf .
