I wrote a PHP chatscript with JQUERY on the userend pullstyle. It reloaded a pull.php page once a second and retrieved only new chat records from my sql database since the last check.However I got an email from my host saying I was using too much bandwidth. Bleh. My chat was working just as I wanted it and this happened. I'm scared to do a COMET php chat because I was told it uses a separate process or thread foreach user.I suppose I just need a strategy that's good, and more efficient than what I had.
