How to start a brand new session after timeout in Struts?

I am working on a J2EE web application that uses Struts and Spring. Problem: When session times out, a login page appears and the user enters the log开发者_运维技巧in information. Then, the application tries to restore the session but there is an exception.

How do I make the application go to the home page AFTER login on all session timeouts (fresh start).

Thanks a lot.
