ASP.NET Internals : Visualizing ASP.NET Page Life Cycle using IntelliTrace

Understanding the ASP.NET Page Life Cycle is an essential knowledge for developing ASP.NET Web Application.

Application Pool then forward the request to worker process to load the ISAPI Extension which will create an HTTPRuntime Object to Process the request via HTTPModule and HTTPHanlder.  Once request passed through the HTPP Pipeline, ASP.NET Page Life Cycle Start.  You will find several articles that describes the What is ASP.NET Page lifecycle, what are the different events fired during page lifecycle.  This post is something different, I will show you how you can see the each and individual Page life cycle events using IntelliTrace
