Problem with Logout: session.invalidate() and close popup

[Giulietta Blumarine]

Hi!
I have a problem with logout function:
I have a principal web page with a button, named "Logout", which calls the function which makes logout and returns a simple html page with written " you are disconnected".
The problem is this:
before calling logout, I could open, from the principal page, a popup or another window!
How can invalidate the session also in this popup or in the other windows opened and show also here the simple html page???

THANKS

Giulietta,
You are invalidating the session on the server. Once it is invalidated, this applies to all pages.

No, because I continue to navigate through the other pages! :-)
How can I do?

Giulietta,
Are you sure it isn't creating a new session and then using that one?
