Websync, .NET and IIS Comet Server
If you are looking to turn your IIS, ASP.NET server into a highly scalable HTTP Comet/Reverse Ajax server, your solution could be called Websync, by Frozen Mountain Software. Websync is cool, because unlike every other comet server currently available, it doesn't require a separate server, instead it runs directly with IIS. It takes about 2 lines in your web.config to get it going, and we've tested 30,000 users simultaneously on a single $400 Acer desktop with 3gig of RAM.

More features include :
- an embedded JavaScript client (only 9 KB!) and .NET client.
- server-side publishers for .NET and PHP
- uses open protocols and proven technology (HTML5, Ajax, JSONP, Bayeux).
- allows secure, controlled access and virtually unlimited scalability.
- offers complete end-to-end application integration.
Websync is a commercial product, pricing start from $749. More information and download at http://frozenmountain.com.
