Determine users currently logged in

[Benedictum]

I need to implement an option to display on the web page for users currently
logged in. How do I implement this in ASP.NET (c#).

I could probably have a boolean field in the database where a user can be
set as logged. This can easily be done in the code-behind. The problem is
how do I "unlogged" the user when the session is timed out?

How are you managing logins...?

If you're using inproc sessions, you can write code in the Session_End
event...

The registered users are authenticated against a datafile. Particulars are
kept in a a seesion var.

Can you show me a code snippet or direct me a tutorial on how to go about
this?
Thanks.

kept in a a session variable.

OK, so when a user logs out, remove them from the session variable.

And, when a session times out, remove the user from the session variable
through the Session_End code in global.asax.

What happens then when the user just closes the browser? How do handle this?

Nothing, as far as the webserver is concerned. That's the nature of the
disconnected architecture of the web.

How do handle this?

You can't...
