title: Laravel 4 handling 404 errors
body: <p>I am new to Laravel and I'm trying to catch any requests that do not match existing routes. Currently I am getting a ...</p>
  
  <blockquote>
    <p><code>Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException</code></p>
  </blockquote>
  
  <p>I have created an <code>App::missing()</code> handler in the <code>app/start/global.php</code> as described <a href="http://four.laravel.com/docs/errors#handling-404-errors">on the documentation page</a> but that doesn't help. I also tried creating an <code>App::error(function(NotFoundHttpException $exception, $code)</code> handler, but that didn't help either.</p>
  
  <p>Any help would be appreciated.</p>
