How to make all frames expired
I have developing a website that have three frames. One frame is under the other frame. Only the 'lowest' frame is active. If the session is expired when surfing that page, all frames should be unload and display login page. Unfortunately, I only can unload until the second frame and the lowest frame, with code document.form.target = "_parent" and post the page to a servlet that contain code session.invalidate(). Unfortunately, the 'uppest' page do not know that 'she' is already expired! Help me with this problem.....thank you.
