Asp.Net MVC 2 - Invalid Route

Once the app is deployed to the web server, I type in an invalid route the mvc app just hangs and then displays a blank page.

On my local IIS, if I type an invalid route I get the exception: "System.Web.HttpException: The incoming request does not开发者_Go百科 match any route.". I want the exception not the blank page.

Any ideas?

It was a missing HttpHandler in the config file. My local config had the hanlder the config on the webserver did not.

<add verb="*" path="*.mvc" validate="false"
