In ASP.NET MVC app, simple custom HTTPModule issue

My first custom HTTP Module, baby step 1 - just getting the plumbing down.

I'm not getting my string in the 200 response but it is there in 304 responses. Can anyone tell me what I'm missing?

My clas开发者_开发知识库s:

namespace WebUI.Models
{
    public class SimpleModule: IHttpModule
    {
        public void Dispose()
        {
        }

        public void Init(HttpApplication context)
        {
            context.EndRequest += OnEndRequest;
        }        

        void OnEndRequest(object sender, System.EventArgs e)
        {            
            HttpContext.Current.Response.Write("rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr");           
        }
    }
}

This is what I'm getting for a request for a css file and there's my "rrrrrr....rrrr" at the end:

HTTP/1.1 304 Not Modified

rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

But the r's don't show in my 200 response for the page's html.

Thanks for any help, Bill

OK, figured out why - Compression. I took it out and now I'm getting the rrrr's in my 200 response. Now I just have to figure out why this is so.

//response.Filter = new GZipStream(response.Filter, compress);
