Question

Meaning I could have the URL routing start at like site.com/v3/site/controller/action

basically it would ignore the v3/site/ and treat that as root?

Answer 1

You sure can. Check out the following routes:

routes.MapRoute("Route1", "StaticFolder/{name}/{id}", new { controller = "Controller1", action = "Action1", name = "Sample", id = "1" });

Route 1 will always invoke Action1 on Controller1 on any requests for resources in StaticFolder.

routes.MapRoute("Route2", "StaticFolder1/{id}/{action}", new { controller = "Controller2", action = "Action2", id = "1" });

Route 2 will always invoke Controller2 with specified action (defaulting to Action2) for any requests to StaticFolder1.

In your case specifically though you want to remove the default route and replace it with the following:

routes.MapRoute("Default", "/v3/site/{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" });
