HTTP Modules

[Peter Morris]

Hi, I'm just trying to learn ASP.NET C# programming from a book.
I'm stuck on the chapter on HTTP modules.

The example in the book shows a fragment to insert into web.config,
plus a program that should be placed in the /bin directory. The book
says this will insert a timestamp into the web page. Actually, all it does
is show an error message in the page

Parser Error Message: File or assembly name SimpleModules,
or one of its dependencies, was not found.

Although the book doesn't say so, I've tried compiling the
given program, as a library, and as a module, I've put both
the source code and the compiled code in the /bin directory,
but I'm still getting the error messages.

I don't understand this. Any idea whats wrong?

Here's the code from the book:

=====================
</configuration>
</system.web>
<httpModules>
<add type="SimpleModules.BeginEnd, SimpleModules"
name="BeginEnd"/>
</httpModules>
</system.web>
</configuration>
=====================

using System;
using System.Web;

namespace SimpleModules
{
/// <summary>
/// Summary description for BeginEnd.
/// <add type="SimpleModules.BeginEnd, SimpleModules" name="BeginEnd" />
/// </summary>
public class BeginEnd : IHttpModule
{
private HttpApplication mApplication;

public void Init(System.Web.HttpApplication application)
{
// Wire up beginrequest
application.BeginRequest += new System.EventHandler(BeginRequest);
// Wire up endrequest
application.EndRequest += new System.EventHandler(EndRequest);
// Save the application
mApplication = application;
}

public void BeginRequest(object sender, EventArgs e)
{
mApplication.Response.Write("<!-- Begin Request Time: " +
DateTime.Now.ToString("HH:mm:ss.fffffff") + " -->");
}

public void EndRequest(object sender, EventArgs e)
{
mApplication.Response.Write("<!-- End Request Time: " +
DateTime.Now.ToString("HH:mm:ss.fffffff") + " -->");
}

public void Dispose()
{
}

}
}
