HttpApplication.LogRequest Event
.NET Framework (current version)
Occurs just before ASP.NET performs any logging for the current request.
Assembly: System.Web (in System.Web.dll)
The LogRequest event is raised even if an error occurs. You can provide an event handler for the LogRequest event to provide custom logging for the request.
For more information about how to handle events, see NIB: Consuming Events.
LogRequest is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
The following example demonstrates how to provide an event handler for the LogRequest event. The event handler also handles several other events. Therefore, the CurrentNotification and IsPostNotification properties are used to determine what code to run.
using System; using System.Data; using System.Web; using System.Web.Security; using System.Web.UI; // Module that demonstrates one event handler for several events. namespace Samples { public class ModuleExampleTestCS : IHttpModule { public ModuleExampleTestCS() { // Constructor } public void Init(HttpApplication app) { app.AuthenticateRequest += new EventHandler(App_Handler); app.PostAuthenticateRequest += new EventHandler(App_Handler); app.LogRequest += new EventHandler(App_Handler); app.PostLogRequest += new EventHandler(App_Handler); } public void Dispose() { } // One handler for AuthenticationRequest, PostAuthenticateRequest, // LogRequest, and PostLogRequest events public void App_Handler(object source, EventArgs e) { HttpApplication app = (HttpApplication)source; HttpContext context = app.Context; if (context.CurrentNotification == RequestNotification.AuthenticateRequest) { if (!context.IsPostNotification) { // Put code here that is invoked when the AuthenticateRequest event is raised. } else { // PostAuthenticateRequest // Put code here that runs after the AuthenticateRequest event completes. } } if (context.CurrentNotification == RequestNotification.LogRequest) { if (!context.IsPostNotification) { // Put code here that is invoked when the LogRequest event is raised. } else { // PostLogRequest // Put code here that runs after the LogRequest event completes. } } } } }
