forms authentication, roles, and profiles application services as Windows Communication Foundation (WCF) services.
• System.Runtime.Caching– Contains types that let you implement caching

• System.Web.Handlers– Contains HTTP handler classes that process HTTP
requests to a Web server. (An ASP.NET Web Forms page -- .aspx file -- is a special form of an HTTP handler.)
• System.Web.Routing– Provides classes that are used with URL routing, which
enables you to use URLs that do not map to a physical file.
• System.Web.Security– Contains classes that are used to implement ASP.NET
security in Web server applications.

Website which is Compiled
• ASP.NET Compiler– All ASP.NET code is compiled, which enables
strong typing, performance optimizations, and early binding, among other benefits.
– Once the code has been compiled, the common language runtime further compiles ASP.NET code to native code, providing improved performance.

ASP.net Application Lifecycle
1. User requests an application resource from the Web server.
2. ASP.NET receives the first request for the application,a class named ApplicationManager creates an application domain.
3. ASP.NET core objects are created for each request.a) HttpContext, HttpRequest, and HttpResponse

4. An HttpApplication object is assigned to the request, if the application has a Global.asax file, ASP.NET instead creates an instance of the Global.asax class that is derived from the HttpApplication class
5. The request is processed by the HttpApplication pipeline.
