HttpApplication class has a method Init. It is virtual and called by ASP.NET runtime when initializing of a HttpApplication is almost finished i.e. all modules have been initialized and all event handlers in the Global.asax have been registered. It is also lat time when you can attach handlers to the HttpApplication events. The method is quite handy if you want to place your custom HttpApplication in a separate class library project.
I’ve used it to see which modules are registered for an application and subscribed for the application events, and how much time each stage of the request processing takes. The output looks like the following.
