Sam,
There are many methods for tracking online users. For example, authlogic has a
last_request_atcolumn which tracks when they last made a request to the site. Though, it’s not very efficient to run a query for that every page load. I personally use Redis for tracking that sort of activity.Here is a great example: Redis in practice, who is online
Hopefully this helps.
