One relatively simple way of doing this would be to maintain a list of “logged in” users in the Application object, together with the time they were last seen. Everytime you inspect the list, you remove any entries that are, say, twenty minutes old…
That’s assuming you are running on a single webserver… If you are running on a web farm, I would have thought you would need to consider recording information as to who is logged in in some central source that is accessible to all instances – a database being the obvious choice…
