.net 4 routing rule help

I have bel开发者_如何学编程ow rule

routes.MapPageRoute("file",
       "f/{Id}",
       "~/file.aspx"
    );

it works just fine if I request site.com/f/11 but when I request site.com/f/11&foo=foo it fails. is there anyway changing this rule so it would ignore & - = - ?

Try using a URL like this: site.com/f/11?foo=foo&anotherparam=anothervalue
