HTTPModule to generate RSS Feed

I am writing a HTTP Module to generate an RSS feed for certain requests. For the moment everything is hardcoded and my code looks like (the idea is - for the moment to generate the RSS feed on the fly for every request - caching is another worry for later):
Public Class rssHTTPModule

Implements System.Web.IHttpModule

Public Sub Dispose() Implements System.Web.IHttpModule.Dispose

End Sub

Public Sub Init(ByVal Application As System.Web.HttpApplication) Implements System.Web.IHttpModule.Init

AddHandler Application.BeginRequest, AddressOf ApplicationBeginRequest

End Sub

Private Sub ApplicationBeginRequest(ByVal objSender As Object, ByVal e As System.EventArgs)

Dim app As HttpApplication = CType(objSender, HttpApplication)

Dim context As HttpContext = app.Context

Dim req As String = context.Request.Path

Dim localPath As String = context.Server.MapPath(req)

If Not (System.IO.File.Exists(localPath)) Then

If localPath.EndsWith("xml", StringComparison.InvariantCultureIgnoreCase) Then



Dim objStream As New System.Web.UI.HtmlTextWriter(context.Response.Output)

objStream.WriteLine("<?xml version=""1.0"" encoding=""utf-8"" ?>")

objStream.AddAttribute("version", "2.0")

objStream.RenderBeginTag("rss")

objStream.RenderBeginTag("channel")

objStream.RenderBeginTag("title")

objStream.Write("test")

objStream.RenderEndTag()

objStream.RenderBeginTag("description")

objStream.Write("beschrijving")

objStream.RenderEndTag()

objStream.RenderBeginTag("language")

objStream.Write("en-us")

objStream.RenderEndTag()

objStream.RenderEndTag() ' channel

objStream.RenderEndTag() ' rss

objStream.Flush()

objStream.Close()

app.Response.StatusCode = 200

app.Response.StatusDescription = "OK"

app.CompleteRequest()

End If

End If

End Sub

End Class

What I want (to start with) is to be able to fire a request to my server www.myServer.com/jef.xml and make sure I generate the XML that has to be returned. Unfortunately, I am not able to do this. My current code is lacking something crucial. (If I execute my current code, IE explorer automatically opens a new favorite box and sharpreader just stops)
 
After trying to read this news article I realized you need to go to
http://www.stevemiller.net and get his free PureText tool which removes
formatting from text copied to the clipboard so it can be pasted as ASCII
text. Its a great tool that sits in the task tray.

Thnk you but this doesn't exactly solve my problem. The formatted code was
intentional.
