Returning a custom 404 page with 404 status in MVC?

Question

I am trying to return a 404 status code with my custom error page. However, I keep getting 200 back since the page is really relevant as far as the browser and server can tell.

What I'm trying to do so far:

<customErrors mode="On" defaultRedirect="~/404" > <error statusCode="404" redirect="~/404"/> </customErrors> 

Where 404 is the route to the controller and the page not found action.

I also tried to set the status code in my action.

 public ActionResult PageNotFound(string locale) { Response.StatusCode = 404; return View(); } 

But it finishes with the fact that page is displayed by default the server error (gray-ish with a red error message text)

Any ideas on how to get around this?

Answer 1

I had the same problem and the solution is posted here :

 public ActionResult NotFound() { Response.StatusCode = 404; Response.TrySkipIisCustomErrors = true; <--- return View(); } 

Answer 2

You tried:

 return HttpNotFound();
