ASP.net Custom Http Modules

Running IIS 7

I'm trying to implement a custom Http Module, what I actually want is to implement gzip compression.

There seems to be a few ways to do this.

I am trying to do this by accessing the HttpApplication.BeginRequest event and add some code there that will use gzip.

I am using umbraco so I don't have a global.asax file so what I have got is a class file inside the app code folder of my website:

public class GzipHttpCompressionModule : IHttpModule
{
public GzipHttpCompressionModule()
{}

public void Dispose()
{}

public void Init(HttpApplication context)
{
    context.BeginRequest +=
        (new EventHandler(this.Application_BeginRequest));

}

private void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext context = HttpContext.Current;
    context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
    HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip");
    HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true;
}

}

Then inside my web-config file I register the module

<httpModules>
..
<!-- Register Custom Http Gzip Module   -->
<add name="GzipHttpCompressionModule" type="GzipHttpCompressionModule"/>
..
</httpModules>

When I put a break point in Application_BeginRequest it never gets hit when I browse the website

Enable IIS7 gzip << The forth Answer down is the technique I am trying to implement.

Any ideas? why this isn't working?

The <httpModules> tag inside the <system.web> tag is only used by old IIS versions (<=6) or when you use the classic mode (not recommended). Use <modules> in <system.webServer> instead.
