Normally when I think of parameters in an URL, I think of the query string. Technically, however, it is also legal to specify parameters in the path segments. Thus given a URL like this:

`http://www.a.com/frisbee/brand`

It is legal to write this instead:

`http://www.a.com/frisbee;color=red;size=small/brand;test=1` 

In practice I never see this. What frameworks, if any, do make use of this?

I'm working with ASP.NET MVC3 of late, and I'm not sure it can extract these kinds of parameters.
