This is more of a general web app development question, so you might get better answers in another group. That said, the short answer is that the session is expired when the session cookie is removed form the browser. Most browsers delete session cookies when the browser closes (not just a single window of that browser). It /may/ be possible to use some javascript to hook into a window close event and expire a specific cookie; but I wouldn’t know how off the top of my head, and it’s possible that it might not work across all browsers. – Regards, John W.
