Missing Session Replication in Tomcat Cluster

[Sunil George]

We have an Application which is Hosted in a clustered environment with Apache web server as load balencer and Two Tomcat Instances on different Windows machines as web containers. We are missing the session object once the request is moving from one server to another. I think it might be some configuration problem. Can anyone help to solve this?
Any help will be really Appreciated.

Thanks in advance,
Sunil
