I'm getting myself acquainted with ASP.Net-MVC, and I was trying to accomplish some common tasks I've accomplished in the past with webforms and other functionality. On of the most common tasks I need to do is create SEO-friendly urls, which in the past has meant doing some url rewriting to build the querystring into the directory path.

for example: www.somesite.com/productid/1234/widget

rather than: www.somesite.com?productid=1234&name=widget

What method do I use to accomplish this in ASP.Net-MVC?

I've search around, and all I've found is this, which either I'm not understanding properly, or doesn't really answer my question:
