Technet Spotlight On Demand Video - Rob Howard - Understanding ASP.NET Internals

You've just been sent to TechEd and were told you need to come back with an understanding of ASP.NET. In this session we provide a very technical walk-through of how ASP.NET works. For example, we walk through the page lifecycle, HTTP Handlers, and more. You'll leave this session with a very good understanding of how ASP.NET works behind the scenes.
