After reading the documentation on AsyncControllers in ASP.NET MVC 2, I am wondering what's the best way to implement an ajax progress bar in this scenario. It seems a bit odd that the tutorial does not cover this at all.
I guess implementing an AJAX progress bar involves requires additional action method that returns the status of the current task. However, I am not sure about the best way to exchange information on the status of the task between worker threads and that action method.
My best idea so far was to put information on the curent progress into the Session dictionary along with a unique id, and share that id with the client so that it can poll the status. But perhaps there is a much easier way that I did not notice.
What's the best way to do this?
Thanks,
Adrian
