I been interested in asp.net mvc since its preview2 release but really its now that I am playing with it. I have downloaded the asp.net mvc preview4 and is currently enjoying the cool new method of developing asp.net websites. An important feature of asp.net mvc framework is its pretty urls and ability to map incomming requests to controllers and action like other mvc frameworks. However the url format like “/blog/archive/hellow-world” would not work on iis6 by default. For these types of urls to work on iis, we either have to setup iis to route all incomming requests to asp.net or use a different url format.
