1 First add the following code to the global application

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingsystem.web;usingSystem.Web.Security;usingSystem.Web.SessionState;namespaceevents{ Public classGlobal:System.Web.HttpApplication { PublicGlobal () {beginrequest+=handleevent; EndRequest+=handleevent; AcquireRequestState+=handleevent; Postacquirerequeststate+=handleevent; }        Private voidHandleevent (Objectsender, EventArgs e) {            //The HttpContext class is used to access information about all applications, requests processed, and requests being built, and its properties currentnotification defined HttpApplication
Subset of Events            stringEventName ="<Unknown>"; Switch(context.currentnotification) { Caserequestnotification.beginrequest: CaseRequestNotification.EndRequest:eventName=Context.CurrentNotification.ToString ();  Break;  Caserequestnotification.authenticaterequest: Break;  Caserequestnotification.authorizerequest: Break;  CaseRequestnotification.resolverequestcache: Break;  CaseRequestnotification.maprequesthandler: Break; //A Change event is triggered when an ASP.
