title: ASP.NET MVC throw and handle error from controller
body: <p>In my controller, for lets say edit user. In my controller, I check if the user has rights to edit then I'd like to throw some kind of authentication or prohibited error which would lead to an error page.</p>
  
  <p>Is there some way to do this rather than creating a controller and action just for error? What is the correct way to do this?</p>
