Hi Arno,
That approach could bite you in the back.
For example: If your session timeout is 30 minutes, and you check each
10 minutes via AJAX, you'll never log out because the AJAX request
"resets" the time-out to a new 30 minutes.
This can all be circumvented (if you know how Sessions work in PHP), but
I would advise the OP to follow Denis's advice and simply use a
window.setTimeout() in JavaScript. Much easier.
