You are starting new thread to process request, but your original thread likely continues execution and successfully terminates request before your new thread even gets to doing something with the response. You have to wait for completion of the new thread in the original thread (you may be able to creatively use asynchronous pages to not block original thread http://msdn.microsoft.com/en-us/magazine/cc163725.aspx).
