Hi all,
I am trying to cluster an application. I found the following
exception stack trace. Hope there are very experts in this group, who
involved in designing of Tomcat container and utilizing the tomcat too.
Please respond me who ever have a very good idea about this.

Don't put request objects in the session. As you have found it will
break replication. Additionally, since request objects are re-used, it
nearly always ends in disaster.
