Is it possible to detect if users are still online? I want to avoid having zomby entries in my online-user-database. When people logout everything is ok but how do I check for the people who just close their browser without logging out?<BR>Should I build some kind of refresh in the page that indicates the user is online? I mean when the user doesn&#039t refeshes in 5 minutes that means he&#039s offline so I cand drop him from the database.<BR><BR>Thanks in advance,<BR><BR>Remco
