From an HTTP request all the way to my files (like .asmx)... what are modules, handlers, app pools... etc... I don't want to ready a chapter about it. Just a summary paragraph.

In IIS, the IIS and ASP.NET request pipelines combine to process requests with an integrated approach. The new request-processing architecture consists of an ordered list of native and managed modules that perform specific tasks in response to requests.
IIS creates a new process. IIS will then provide the query string and other parameters that are included with the request through the environment and standard input (STDIN) handle for the process. ISAPI filters are always loaded as long as the Web service is running and a request to the server has been made.
NET Framework 4.5 is the default on IIS 8.0.
IIS Architecture IIS has two main layers - Kernel Mode and User Mode. The Kernel Mode contains the HTTP. SYS and User Mode contains WAS and W3 service.
