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.
Imports System Imports System.Data Imports System.Web Imports System.Web.Security Imports System.Web.UI Imports Microsoft.VisualBasic ' Module that demonstrates one event handler for several events. Namespace Samples Public Class ModuleExampleTestVB Implements IHttpModule Public Sub New() ' Constructor End Sub Public Sub Init(ByVal app As HttpApplication) Implements IHttpModule.Init AddHandler app.AuthenticateRequest, AddressOf Me.App_Handler AddHandler app.PostAuthenticateRequest, AddressOf Me.App_Handler AddHandler app.LogRequest, AddressOf Me.App_Handler AddHandler app.PostLogRequest, AddressOf Me.App_Handler End Sub Public Sub Dispose() Implements IHttpModule.Dispose End Sub ' One handler for AuthenticationRequest, PostAuthenticateRequest, ' LogRequest, and PostLogRequest events Public Sub App_Handler(ByVal source As Object, ByVal e As EventArgs) Dim app As HttpApplication = CType(source, HttpApplication) Dim context As HttpContext = app.Context If (context.CurrentNotification = RequestNotification.AuthenticateRequest) Then If Not (context.IsPostNotification) Then ' Put code here that is invoked when the AuthenticateRequest event is raised. Else ' PostAuthenticateRequest ' Put code here that runs after the AuthenticateRequest event completes. End If End If If (context.CurrentNotification = RequestNotification.LogRequest) Then If Not (context.IsPostNotification) Then ' Put code here that is invoked when the LogRequest event is raised. Else ' PostLogRequest ' Put code here that runs after the LogRequest event completes. End If End If End Sub End Class End Namespace
