Does anyone know how to code up long-polling AJAX requests (for server PUSH notifications) in ASP.NET MVC? Whenever I do it, it seems that only the last browser to open up a window gets the notifications. As if IIS/ASP.NET were canceling the last request because it was hung or something.

I recently wrote a simple example of a Long Polling Chat Server using MVC 3 Async Controllers based on a great article by Clay Lenhart
You can use the example on a AppHarbor deployment I set up based on the source from the BitBucket project.
Also, more information available from my blog post explaining the project.
