Question

We have a RESTful API that we are doing in MVC3. We would like to have routing versions to go to different controllers. Our current routing is:

routes.MapRoute("api1", "{controller}/{action}/v1");
//routes.MapRoute("api2", "{controller}/{action}/v2");

In the future, when we make a version 2… what is the best approach to making sure v1 api goes to controller v1 and v2 goes to the version 2 apis?

Thanks.

You can hardcode the controller into the route

routes.MapRoute("api1", "{action}/v1", new { controller = "V1" });
routes.MapRoute("api2", "{action}/v2", new { controller = "V2" });

I would disagree with the other poster that versioning in the URL is necessarily a bad idea. URL versioning is more flexible in terms of output caching.
