Goal

Is it possible top preserve the session across multiple applications deployed to different clusters?

Environment:

• Configure 2 weblogic clusters clusters each with an application that uses the same http session.
• An Apache web server with the WebLogic plug-in is used as a load balancer in front of the two WebLogic Server clusters.
• Coherence*Web is used for http session management.

Scenario:

1. Login to cluster1/app1 to create session
2. Switch to cluster2/app2 - coherence web will get the session
3. Switch back to cluster1/app1 - it's possible for the user to go to another jvm that does not have the session - coherence web will get the session - but you can get the user sessions on several of the jvms
4. Switch back to cluster2/apps - its possible for the user to go to another jvm that does not have the session - coherence web will get the session - but u can get the user sessions on several of the jvms

The JSESSION primary jvm is only preserved when the user stays in the same cluster/app
