asp.net mvc 3 - MVC3 MapRoute, parameter with slashes -

how create maproute accepts slashes without considering new parameter? if url is

http://localhost/root/p1/default.aspx 

i want 1 parameter pick after localhost (root/p1/default.aspx). take 3 parameters because there 2 slashes, , maproute separates parameters slash. if route looks like

routes.maproute(    "urlmaproute",    "{path}",    new { controller = "home", action = "index", path = "default.aspx" } ); 

then {path} picks everything, though url contains slashes.

you use catchall route:

routes.maproute(     "urlmaproute",     "{*path}",     new { controller = "home", action = "index", path = "default.aspx" } ); 

and then:

public actionresult index(string path) {     ... }
