Trap BrowserClose event so can Logout Session

[Ron J]

How can I trap the user just closing the browser (upper right [x]) so I can
shutdown the Asp.net session properly. Don't really want to wait for the
default timeout to occur. I'm using a Master page so it should be easy to
logout once I know how to catch the event. Thanks.

You can't.

This question comes up regularly - there are usually several suggestions,
mainly centering around the onunload event of the <bodytag - none of them
even half works.

Don't waste any time on this - it isn't possible, otherwise every website in
the world would be doing it...

Thanks Mark. Fair enough. Perhaps you can suggest another way to do this:
User logs in at one station.
They move to another station and want to login.
We don't want concurrent logins from different stations.
-how do I logout the first one? I know timeout but thats 20minutes.

I suppose you could store the remote IP Address of the machine when they
first log in (you could store it in Cache with a key that matches the
username).

So if you look at the UserHostAddress inside Application_AuthenticateRequest
and compare, that would be one way to do it.
