implementing asp.net mvc chat full duplex
I want to create a Facebook/Gmail like chat me for my social network.
I'm looking for the best technique to achieve it. I found several libraries, but I do not know what the most appropriate
The prerequisites are:
- framework c#
- low bandwidth consumption
- chat integrated into the site, if the user changes page, the connection should stay alive
- Free library (not paid)
- shared hosting, can not install nothing on web server
- if possible take advantage webSocket for browsers that support it and fall back to flash or similar automatically if not supported
- one to one chat
- If possible I would avoid Silverlight (with full duplex wcf) and use HTML / jquery chat
- compatible with all browsers
I found the following libraries, but many do not provide a c# implementation or need to install a COMET web server or need to install components on web server

I believe that use a technique such as Reverse Ajax consume a lot of bandwidth, right? What is the best,free,documented and c# implemented libray with low consume of bandwith that you would use?
thanks
Personally, until you have measures that you need things like comet, I would use basic JSON polling with things like throttling (so you slow down the polling on quiet rooms). And a very basic "nothing had changed" message. For an example, click the "chat" link above. It is simple and pragmatic...
Re keeping between pages; trickier especially if you don't want Silverlight. We use a few HTML 5 tricks there to avoid hammering the connections.
