Fiddler and the Visual Studio Development Server

If you are like me and are addicted to using Fiddler to debug HTTP sessions, you may be a little frustrated by the fact that you can't do this using Visual Studio's built-in HTTP server. Well, Dominick supplies an answer that he found on a German blog:

IE7 always bypasses proxies for "localhost" addresses. Regardless of configuration. Now when you want to use e.g. Fiddler with a local web app, this can become an issue.

If you are using IIS it's easy, just use the local machine name instead of "localhost" (something I usually do anyways because of SSL). But Cassini doesn't accept machine names - the (quite funny) workaround for that is to use "localhost." (note the dot) instead. Works fine....
