This sounds interesting. Maybe have you example code?

2) You can have code to return false from the window.onunload event so the user
gets a "are you sure" popup and just remove the listener when the click on a
command link or button

Thanksfor the reply. What I am looking for is: I want to vorbiden the back
button activity, i.e., if the user click the back button, it will show error
message and the user has to refresh the page and go back to the page where he
starts.
This must be possible since I find many web-apps do so.

I can even access the page by clciking the back-button in the browser tool
bar. Now I want to caoture this action so I can check if the session is valid
or not redirect it. This might be happening *just* within your browser,
without any requests going to the server. If that is the case, then there is
nothing you can do on the *server* to catch this. If the browser is
actually fetching the previous page from the server, then you have something
incorrectly configured in your servlet container security settings, as that
should not be possible. Regards, Simon
