Application Timeout and Session Timeout

Hi,

I've successfully integrated my WD application into the portal. I'm trying to set an application timeout for my WD application, wherein if the application is idle for a long period of time say 20 mins... then it should go back to the login page and prompt the user to re- login. Currently, if I click on the refresh button the application is allowing the user to view from the same page where he was. Is it possible to synchronise this application idle timeout with my portal session timeout. If so then where do I configure it or write the code for.

Please help.

Thanks,
