Introduction

This post shows how to set up ASP.NET MVC routing so that all URLs are directed to a single controller action.

Catch-All Route

This will make the URL always go to the Home Controller's Index action.

routes.MapRoute(
                "AllUrl",
                "{*url}",
                new { controller = "Home", action = "Index" }
            );

Defining Specific Routes Before the Catch-All

This route will catch all URLs, but if you have any other URL you need to define, place it before this one. For example, if you want to define a test URL so that when the URL hits /test, it will go to the Home controller's Test action:

routes.MapRoute(
               "TestRouteName",
               "test",
               new { controller = "Home", action = "test" }
           );

  routes.MapRoute(
                "AllUrl",
                "{*url}",
                new { controller = "Home", action = "Index" }
            );

Conclusion

Using a catch-all route with {*url} in ASP.NET MVC allows you to direct all URLs to a single action. Just remember to define any specific routes before the catch-all route, since routes are evaluated in order and the first match wins.
