It won't do anything for the client side, though.Basically, the problem is that while a standard web browser can contact a server and *ask* for updates, the server isn't able to contact the browser and say hey, I've got some news for you!The usual way of solving that problem, is to have the client computer run some Java applet or stand-alone application that allows for true two-way communication.An alternative, cruder, method is to use JavaScript or even plain html to get the browser to request updates regularly. The main problem with that solution is that any realistic update frequency would mean a big (with JavaScript) or *ENORMOUS* (with plain html) waste of processing power and bandwith. It might still be good enough for your purposes, though - depends on how much traffic you'd expect.Apparently the pluto.no chatroom uses plain html - no wonder it doesn't seem to be very popular.Frank Nordberg http://www.musicaviva.com ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
