Custom httpModule is not logging to Windows Logs

Question

I have a problem with logging an message to EventViewer\WindowsLogs using a custom HTTPModule class. I've already try to run Visual Studio with admin rights, I also tried from IIS 6.0. It doesn't crash, it just doesn't add any code. Below it's the module class and the config file.

HttpModule

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Diagnostics;

namespace Chapter_V.HttpModules
{
    public class MyHttpModule : IHttpModule
    {
        public void Init(HttpApplication application)
        {
            application.AuthenticateRequest += new EventHandler(OnAuthentication);
        }

        private void OnAuthentication(object sender, EventArgs e)
        {
            string name = HttpContext.Current.User.Identity.Name;

            EventLog log = new EventLog();
            log.Source = "My First HttpModule";
            log.WriteEntry(name + " was authenticated !");
        }

        public void Dispose()
        {
        }
    }
}

web.config

<?xml version="1.0"?>
<configuration>
    <system.web>
      <httpModules>
        <add name="MyHttpModule" type="Chapter_V.HttpModules.MyHttpModule,ChapterV"/>

      </httpModules>
    </system.web>
  <system.webServer>
    <modules>

      <add name="MyHttpModule" type="Chapter_V.HttpModules.MyHttpModule,ChapterV"/>
    </modules>

  </system.webServer>
</configuration>

Do you have any ideea about this issue? (this is only for study purposes)

Provided the user identity on your application pool has the rights to create event log entries. Try running the following script:

eventcreate /ID 1 /L APPLICATION /T INFORMATION  /SO "My First HttpModule" /D "My first log"

This will create a new event source named "My First HttpModule" under APPLICATION event log as INFORMATION event type.

Not sure of the exact reasons why, but a source must already exist (be created) in the event log before it can be used in code.

Thank you, Brent. That line added an event log in the APPLICATION event log. I still don't get it why it doesn't want to add a log using my Http Module. I try it with the Visual Server web server (CTRL + F5) and also from IIS. But no success. – Cosmin Mar 05 '14 at 20:36
