Re: Desperate Help needed

You probably has configured your chat client page to make a timely refresh, so the user can get new messages every time the page is refreshed. I don't know if you allow the user to set up the refresh interval, any way you can have a logged users table with their login time and last refresh time. If current time is (for security) n times the refresh interval ( say twice ) you may log them out. Be careful with users connection speed ! You have all the control of your database so you know if the user didn't refresh the chat page in the last n refresh period. Messy ? HTH.

How do you detect if a person has closed the window (hence killing the cookie) without logging off (so the database still has him listed, and therefore is shown to be online)? Here's the scenario: 1. one table lists the chatters' names 2. second table has 25 rows for each messages, they keep getting replaced as the new messages come in the problem: the chatters table lists those users who logged out ages ago... thanks.
