Get currently online users?

After googling a bit I have found some tips about how to get online Users with ASP.NET. But I am using my own class for membership.

The information I have found is:

  1. Log the users sessionId to database when the user logs in
  2. Log them out when their session time out

What is your advice about this?

We use this approach at work so that when users upload data in separate but concurrent session to a webservice, we can catch 90% of the cases where timeout has occurred and warn the user then and there.

We don't catch every case because:

  • Session timeout event handler in global.asax isn't reliably called the moment expiration occurs (IIRC)
  • The user could have closed their browser window in the mean time.

Two common approaches of which I am aware are:

  • Any user action causes an update to LastActionTime in the users table. Using this value + 20 minutes (or whatever your session timeout value) is a pretty good indication of who is logged in
  • A small AJAX panel updating every few seconds (linked with the previous option).
