So i was wondering what an application pool is in IIS so thought i should read about it. So if you dont know about Application pool this is the post.
So in my words application pool is like pool is like a pool where you can find worker process. Now these worker process are process which belog to your web site, web service or web application. Each application pool can have one or more worker process which is good in case of resource sharing but not so ideal in some cases when refering to performance.
In application pool you can either share the resources or isolate them among worker threads. In both cases it serves the pur pose.
