Commented Issue: HttpResponseException doesn't work in custom IHttpRoute implementation [387]

I have a custom IHttpRoute implementation for doing some custom routing. I want to throw a 400 (bad request) sometimes. I tried to do a "throw new HttpResponseException()" in my code but the client always receives a 500.
