[Muhammad Sarwar]

Hi All,

I am in a situation where I need to use the session information of IBM Websphere Portal on some other application server for verifying the validity of user session.
The senario is like.

1. I have Websphere portal where user logs in.
2. I have legecy systems for that user is redirected to another application server (SUM8) from websphere portal.
I would like to design a solution to verify users session validity on Websphere portal while I am at SUNONE8 application. On SUNONE server I have few information about user ...like session id at WS portal ,user ID

I appreicate any help from you people.
