Multiple Instances of w3wp.exe
I don't understand why there are two ASP.NET w3wp processes in Task Manager when I only have one website and one application pool. Why are there two processes running? I have Googled this and looked on MSDN but cannot find an answer.
I am trying to debug a memory leak in an application. I understand the concept of threading and multiple threads living in a process, but I do not understand why there are multiple processes.
I am specifically asking what scenarios can cause more than one process to run.
