MVC Routing For Specifying Response Type

This is a post I wrote about providing a response type based upon the extension used in a route for MVC routes. Example URLs: /Category/Show/1 /Category/Show.xml/1 /Category/Show.json/1 With this approach, in your controller, RouteData["responseType"] will default to html or if a different extension was added to the action, then it will reflect that extension. This allows nice URLs for services wanting to access your actions as services that provide json, xml, or whatever else you might desire to return.
