Bruce, what I have been trying to explain is that this _can_not_ be
overcome. The web is stateless. Connections between server and client
last only long enough for a file to be requested and sent, once that has
happened the server and client are no longer connected and have no
knowledge of each other. _No_ server-side program will be able to tell
you when a user closes their browser or goes to another web site. HTTP
simply doesn't provide what you are looking for.
