How asp.net knows that my asynchronous handler is finished?

Hi



I have a class implementig IHttpAsyncHandler, the class start a asynchronous
in the method BeginProcessRequest, all works fine.



But I have a doubt:



How asp.net knows that my asynchronous request has finished? Is doing
polling over the IAsyncResult returned by BeginProcessRequest or is doing
something more smart?



If is doing pooling, which is the thread doing this operation? A thread of
ThreadPool, I suppose not, because in this case will the trhread will be
blocked until the operation finished.





Thanks in advance

Javier
