ASP.Net: HTTP 400 Bad Request error when trying to process http://localhost:5957/http://yahoo.com

Question

I'm trying to create something similar to the diggbar.

I'm using Visual Studio 2010 and Asp Development server.

However, I can't get the ASP dev server to handle the request because it contains "http:" in the path. I've tried to create an HTTPModule to rewrite the URL in the BeginRequest , but the event handler doesn't get called when the url is http://localhost:5957/http://yahoo.com. The event handler does get called if the url is http://localhost:5957/http/yahoo.com

To summarize:

• http://localhost:5957/http/yahoo.com works
• http://localhost:5957/http//yahoo.com does not work
• http://localhost:5957/http://yahoo.com does not work
• http://localhost:5957/http:/yahoo.com does not work

Any ideas?

I've written an article with Stefan's help that explains how to do this:
