Is a asp.net web application (hosted in IIS) considered a process?
And this process is in an application pool.
And there can be 1 or more application pools in a app domain?
Is this correct?
An app pool in IIS is a process (w3wp.exe), and an app pool can host several applications.
So, no, an ASP.NET application isn't considered a process, but it can be the only application hosted in an app pool.
Note: I'm only considering IIS 6 and up.
