            <description><![CDATA[Hmmm... clever... Kind of dirty, but clever, I'll give you dat. A nice, little, invisible agent in the client. Still, there's a lot to consider with this approach, I think. Didn't thought about it long enough, but I sense that openning two browsers...]]></description>

            <description><![CDATA[Using a tiny flash movie (or applet) in a frame, you could open an XMLSocket to a server. As soon as the browser window gets closed, it will disconnect. That's probably the most correct way to do it, but it a) might give permission troubles b) requires a...]]></description>

            <description><![CDATA[Perhaps you could implement your own isOnline() criteria... No matter the session timeout, if the user has not performed any action for some time, show it as &quot;offline&quot; (or &quot;away&quot;).<br>This could be accomplished using a combination of...]]></description>

            <description><![CDATA[I don't think session timeout is a good way to determine if a user is online, cuz that's like 30min. It's too long, maybe a user has been on for as little as 5min, and 25min afterwards it'll still be showing as if he was actually on.<br><br>I can't set...]]></description>
