Asp.net underground Architecture

I started refreshing my .NET architecture again. One of the article i come across is the Low level details on how ASP.NET works.

Ultra light cool details for laymen understanding. Highly recommend.

Start To Finish how .aspx page request has been handled

-IIS gets the request
-Looks up a script map extension and maps to aspnet_isapi.dll
-Code hits the worker process (aspnet_wp.exe in IIS5 or w3wp.exe in IIS6)
-.NET runtime is loaded-IsapiRuntime.ProcessRequest() called by nonmanaged code
-IsapiWorkerRequest created once per request
-HttpRuntime.ProcessRequest() called with Worker Request
-HttpContext Object created by passing Worker Request as input
-HttpApplication.GetApplicationInstance() called with Context to retrieve instance from pool
-HttpApplication.Init() called to start pipeline event sequence and hook up modules and handlers
-HttpApplicaton.ProcessRequest called to start processing-Pipeline events fire
-Handlers are called and ProcessRequest method are fired-Control returns to pipeline and post request events fire
