asp.net asynchronous comet long-polling reverse-ajax

ASP.NET asynchronous controllers and long polling

I've been looking for IIS based solutions for comet/push/reverse-ajax pages, and came upon asynchronous controllers

It seems like that allows xhr long polling without the problem of running out of threads, am I correct? Does this allow fairly decent scaling for long polling pages?

Solution

I would say take a look at signalR. Nodejs for iis is also an option
