Chat Application

Question

Hi, I am creating a chat application using ASP.Net and C#. The chat room has frames...and one frame is chat box ---which shows all the messages.. To keep chat box keep collecting the messages and showing it... a meta tag of refresh (may be 2 secs. or so ) is required. This mechanism works fine. But i need to know and implement of some other mechanism by which the chat box can keep listening and collecting, showing the messages. As the refresh method looks bad refreshing the frame again an again showing that blue progress bar in the browser...moreover i dont find it to be efficient in terms of performance. I am using .Net remoting concept... but help can also be provided for web service or whatever you find suitable. If any details please contact - [email protected] Thanks in Advance . Regards, Uxi
