Catch Exception when non-existant controller is requested

Question

I want to be able to capture the exception that is thrown when a user requests a non-existant controller and re-direct it to a sweet 404 page. How can I do this?

For example, the user requests http://www.nosite.com/paeges/1 (should be/pages/) they get re-directed to the 404 rather than the nasty exception screen of death?

Answer 1

Take a look at this page for routing your 404-errors to a specified page.

Answer 2

Just use a route:

// We couldn't find a route to handle the request.  Show the 404 page.
routes.MapRoute("Error", "{*url}",
    new { controller = "Error", action = "404" }
);

Since this will be a global handler, put it all the way at the bottom under the Default route.
