title: Break Out of an ActionResult without Redirect
body: <p>Is there a way to do a straight break-out from an ActionResult method?  I'm running some manual verification in my form's submit controller.  If validation fails, I want to exit out of the method.  No redirect, nothing.  Just stop it in it's tracks and exit out.  Something like a break or exit.  Does that exist, or do I have to have a return Redirect()?</p>
