thanks planoie for sharing

the idea is still not cleared(smooth refreshing )
did you see the file update.js
i think there is a functions that is stange to me,it's used for updating frames.....

the smooth refresh in previous mentioned site(conqurechat) is the new difference from all simple chat scripts which use traditional <META HTTP-EQUIV='Refresh' CONTENT='10; URL=file.asp'> to refresh page..

all i need is some clear view for that script (i am not so good at jscript)

What do you mean when you say "smooth refresh"? The smoothness of a page refresh mostly depends on how the browser renders a page. Changing the way it refreshes isn't going to help. Refresh is refresh. I'll bet if you dug down enough into that code that you'd see there are just meta tag refreshes and javascript refresh calls in it. Nothing more complicated than that.

thanks planoie for your patience keep replying to me

below is that jscript code (which i think update functions used)

he also call Refresh function as.. executeRequest('action=refresh');
