sessionhandling question

[Hansjörg Meuschel <hj...@gmx.de>]

Hi there,
I've a very special question: I need to make sure that, after going to 
an overview page, the user can't go back to the previous pages and 
perform actions there.

I thought about invalidating the user's session and assigning a new one 
(I've a filter which redirects invalid sessions to the login page)
- Can this work?? I know how to invalidate a users session but how do I 
retrieve a new one (and how do I set it in context? ?
- Or is there any other possibility to realize this?

I know this is not quite myfaces related but if anybody could help I 
would be very thankful!!
See ya,
Hans
