We know that in ASP. To initialize an ASP. NET application and make it handle requests, you must perform some processing steps to familiarize yourself with the application lifecycle so that you can write code at the appropriate lifecycle stage to achieve the desired results. Never do anything that will only drag the control. NET programmer, never! Then you have to understand the ASP. NET

programmer p_ Module can register a lot of events, such as commonly used beginrequest, EndRequest, AuthenticateRequest, AuthorizeRequest and so on, there are some other infrequently used events we will not repeat. All in all, HttpModule is strong enough to be involved in all events that can intervene throughout the application cycle---because it is fully licensed. The following is a sample code for registe

NET web sites are developed with Web Forms, MVC, Web Pages and hosted in Internet Information Server (IIS ). when there is a page request, for example: http://www.example.com/index.aspx , IIS will use its Internet Server

This ensures that events that receive user-related actions are processed sequentially.Main Run Loop handles the event's schema diagram:User-operated devices, related operation events are generated by the system and distributed through the specified port of Uikit. Events are queued internally and distributed to main run loop for processing. The UIApplication object is
