I have four applications (A, B, C and D) running under an application pool Pool1.
- Will all applications in that pool run under separate worker processes?
- Will all the applications run separate instances of
w3wp.exe? - Will all of them have their separate
APPDomain?
My understanding is that each application pool will run it’s own worker process so websites A, B, C & D in the same app pool will share a worker process. Within the single worker process each website will run in its own AppDomain.
There is a pretty good description here: Difference between an application domain and an application pool?
