Weblogic session expiry issue

[Kannan]

Hi,
WLS version: 8.1.3.0
IE version: 6.0.2800.1106

we are facing a strange issue with IE/Weblogic session management.

We have two installations of WLS 8.1.3 on two boxes hosting same
application ear. When we try to access this application from
IE/Mozilla, we are seeing different results

1. On server ONE, with IE the session is expiring after first time we
hit a link (i.e. session.getAttribute("isActive") == null). After the
creation of the session, the URL is of the form
http://<server>/webApp/workflowDetail.do;jsessionid=CGndx67l68wT3WLD3yggrHt2fJbn7fQXQ0mhP1FQrL818wfb22FQ!1685253770


The jsessionId is attached automatically to the URL. After hitting this
link, the URL looses the jsessionId, i.e. it becomes
http://<server>/webApp/retriedWorkflowList.do
This results in a session expiry, i.e. WLS server is not able to relate
this to previous session.

Experiments we did to narrow the problem:
2. On the same server ONE, with Mozilla, everything works fine and the
URLs are always of type
"<server>/webApp/retriedWorkflowList.do?<get-params>"

3. On server TWO, using the same IE, everything works fine and the URLs
are always of the type
"<server>/webApp/retriedWorkflowList.do?<get-params>"

The WLS instances does not have any configuration difference. The
strange things are
- same IE works on server TWO i.e. any cookie related issues should not
arise
- Mozilla works with the server ONE implying WLS configuration should
not be an issue

I am really not sure as what is causing this, but it looks like using
IE one of the WLS instances is not able to recongnize the session. Does
anyone has faced this issue and knows on how to solve this issue?

Thanks,
