I’ve been, fruitlessly, trying to extend the login code from the Agile
book. What I’m trying to do, is create a list of logged in users.
My idea is to the list of sessions. However, many sessions seem to be
outdated. I believe the best way would be to get a list of sessions that
have been active in, say, the last 15 minutes.
Question is: how can I do this? Any hints would be greatly appreciated.
