Repeating a Parameter in a ASP.NET MVC Route

Question

I am trying to write a route that matches the following URL format:

/category1/category2/S/

where the number of categories is unknown, so there could be 1 category or there could be 10 (1..N).

I cannot use a catch all becuase the categories are not at the end of the URL.

I am actually routing to a web form here (using Phil Haack's example http://haacked.com/archive/2008/03/11/using-routing-with-webforms.aspx), but that is beside the point really.

Any ideas?

Answer 1

I think it's impossible but you could try work around it using this route:

{categories}/S

Then split the categories using the '/' character yourself.

I made a site where I just fixed it to 1-3 categories by registering 3 routes, but I had to work around a lot of things and wasn't really happy with it afterwards.

EDIT: Using S/{*categories} will catch the categories. You can only use it at the end of the URL.
