Custom httpModule is not logging to Windows Logs - asp.net

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)

Answer 1

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.
