Problem With Apache and Tomcat

Dear All,

Last around a month we are facing major issue.

We are having 2 Tomcat Servers running (On diffrent PC).

We want to add single sign on facility hence we We are running an application on one tomcat which carry out all Authentication & related Jobs. We can call this just like portal concept.

Other tomcat(s) is/are having applications running.

When User (Few / Particular users only) accesses an appication through portal, He/she dose not get any response (For Complecated / Heavy Weight JSPs only) small screens are visible.

When user accesses the same dirctly (bypassing the portal), response is recieved.

This code Was working for more than 3 years when both tomcats are running on same server (diffrent ports). Problem started When we Isolate them.

Its not working when we revert the sepration of servers

We used Apache Sever for virtual Hosting.

Can you help me to resove this???

Finally this issue has got resolved.

We were using Apace proxyPass for redirecting. It sucks..

Then we have integrated Apace - Tomcat with loadbalancer Using mod_jk.
