When ASP.NET starts up your application, it creates an instance of your application's HttpApplication
implementation, which is represented by Global.asax. It then uses reflection to look for methods named appropriately with the correct parameters, that match each of the events. Those it finds, it attaches as event handlers automatically for you.
