显示“实时”评论的最佳方法

I want to show user comments in a grid (easy enough) but I want to show the new records as they come in as well. In theory, the user stays on this page a while, adding their own comments and viewing others' as they come in.

It behaves very much like a chat window with multiple users making comments, though I don't expect it to be as active as one (I expect it to be about as intermittently-updated as a Facebook wall)

I've considered: - jQuery+AJAX+Timer?
- Web Sockets. Are Web Sockets ready for prime time? And can Web Sockets be implemented with ASP.NET + IIS?

I'm looking for a solution that is elegant, clean, fast (low bandwidth; only load the new comments if possible, popping off the older ones) and not so esoteric on an ASP.NET/IIS platform...not sure how to go about this, kindly requesting your help.

Thanks!

PS I tried searching on "comment system" "show new records" "chat systems", but couldn't quite hit the results I sought.

    Try this

    var interval=2; // on page load

    ajax syncing with server for every 2 seconds and on mouse || keyboard event reset interval to 2 and every 10 ajax calls increase the refresh interval by 1 sec. This way you can control server load. and will save bandwidth for client and server.

    These values can be adjusted as per your needs
