I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging.

An old url (with UrlRewriting) would be:

http://www.mysite.com/Category/Arts-and-Crafts_17

I now have a MapPageRoute defined in global.asax as:

routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx");

This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like:

http://www.mysite.com/Category/Arts-and-Crafts_17/page/2

But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?
