Portlet Session Replication related query

[rinku05]

I am using jboss AS 4.2.1, jboss portal and apache2.2 for clustering setup.
I am successful in achieving the clustering. My test scenarios are:
Scenario1:
1. start the jboss application server and apache server on both the machines.
2. login to the site, minimize the portlet say on pageA.
3. stop the server which served this page.
4. You will be still on the same pageA with portlet still minimized(as desired)
5. click on different tab, now come back to the pageA. Now the portlet size is not the minimized one but the original one.
But if before performing step5 you refresh the page, portlet size on pageA would minimized one.
Is this the expected behaviour?

Scenario2:
I have one more issue:
1. start the jboss application server and apache server on both the machines.
2. login to the site.
3. click on different tab to get pageA
3. stop the server which served this page.
4. You will be still on the same pageA
5. Now click on logout link.
You'll be taken to home tab ie default tab. If you click logout now u would be looged out.
But if before performing step5 you refresh the page, and now click logout, u'll be logget out.

Please help me.Please reply.Its very urgent.

First, clustering problems are hard to solve using community forum as setup required to produce your issue is time consuming and not easy. This is when you should buy support contract. In your case, it fits more because you said it's "very urgent".

You did not mention which portal version you are using. If you heed to my previous suggestion then you should be using JBoss Enterprise Portal Plantform (EPP) 4.3. On community side, use Portal 2.7.2 with AS 4.2.3. These versions have lots of clustering fixes.
