Hi Luis,

can you explain what you are trying to do? This will make it easier to answer.

If I guess: you want to invalidate the session and log the user out? I.e. something like a log-out button? Is that correct?

Thanks,
Elias.

Hi Luis,

Your approach: session.setMaxInterval(1) is a good idea. However the PhaseListener is not appropriate (it gets called on every request!). Here is an example that uses a clickable "Logout" link.

Hope this helps,
Elias.
