HTTP Question

Is IIS Http daemon?

I was reading about http daemon and in order to make sense of it I tried to relate it to something I know and I thought that based on its definition it is very similar to IIS, so can we consider the IIS an HTTP daemon or does the IIS include it? I would appreciate it if anyone can clarify the relation between them.

Answer

Windows has a service called the HTTP Stack (http.sys) which is responsible for routing HTTP requests to the proper process, such as IIS.

When the IIS service runs, it registers any URLs that it wants to handle with http.sys. This makes it possible to have multiple processes share port 80 as long as they request different URLs.
