How does MVC handle querystring parameters?

Question

This is what I'm trying to do. I have a route defined like below.

     <route name="productresultscatchall" url="ProductResults/{*querystring}" controller="ProductResults" action="Display"/>

My urls get constructed by a non-MVC page that has no idea about my routes. It passes in everything as a BIG querystring.

e.g.

www.abc.com/ProductResults/productid=249&categoryid=38&producttype=xyz&sorttype=1&showdesc=false

The querystring param combination can change and there is no way I can change the incoming url to a SEO-friendly route.

My end goal is to get every possible querystring param that is passed and use it (if available). What I do not want to do is create an Action method that accepts all combinations of parameters. The Action method will use a helper CurrentRoute.GetValue(paramName) to retrieve values.

Does MVC pass in the querystring parameters that can be accessed via the controller?

AFAIK you can bind querystring parameters to controller method calls, like they were POST variables.
