[Javascript] Please help with a window closing problme

[javascript@xxxxxxxxxx (Roland Dong)]

How can I have the user redirected to another page after the user closes the
window by clicking he cross on the upper right corner or upper left corner
of a browser?

Of course I could add javascript close() to close the window.  But sometimes
users like to click that little cross to close the window. When that happens
I want the user be redirected to a new page. How can I do it?

Thanks

Roland
