ASP.NET MVC: Routing hierarchy URL

How开发者_开发技巧 can I make routing for this?

URL: /category/main/sub/ or /category/main/sub1/subsub/

I want to have /main/sub/ and /main/sub1/subsub/ as parameters in Index action method of CategoryController.

Found the answer:

Should use "/category/{*path}" instead of "/category/{path}" in the routing path.
