function AFTER window close.

On my page I have a login section set up. If the login is valid a cookie is placed on the users machine so that they may freely view the restricted area. When the "logout" the cookie is deleted. Every page that I chose checks to make sure users have this cookie and if not they are redirected back to the login page (which itself closes after 20 seconds or 3 invaild inputs). HOWEVER, if the user doesnt click logout the cookie stays there. I am looking for a script that knows when the window is closed so I can call the delete cookie function. Basically a script to execute after a window has been closed. How do I do this??

Have you checked into the onunload event?

Excellent. Didnt even think of it

Thank you good sir.
