How to end a session immediately when the browser closes?

#1

Hi everyone,

Sorry for cross-posting this message. My mistake.

I need some help (may be in the form of some sample code) for the subject
question.

I have an ASP.NET/C# application. I need to do quite a few tasks when the
session ends. I don't want to depend on the session timeout factor since it
may end too soon or it may hang around too long. I can't find any event
that fires when the browser closes. The Session_End event handler in the
Global.asax does not execute until the timeout value expires. Also, when it
does execute the Session_end, it seems that the session has already ended
and so, I have no access to any of the session variables I was holding onto.

Can anybody tell me the server side sequence of events and their handlers
that get called when the user closes a browser? Does the browser inform the
server that it is closing, so that I can do my cleanup?

Any help is highly appreciated.

Babu.

There is no such event. What are you trying to accomplish? Maybe there is an
alternative approach. As far as the architecture is concerned, when the
server doesn't hear from the client after a given amount of time, it assumes
the client went away and initiates cleanup by firing the session end event.

Thanks for the input guys!

I understand that when the timeout kicks in, you could do the necessary
cleanups in the Session_End. But I still find it a little bit surprising
that the browser does not somehow inform the server from which the page was
fed, that it is closing or the user has navigated out of the site. I would
rather like to do the cleanup and end the session immediately once the user
has closed the browser or moved on to some other website.
