title: Override HTTP header's default settings (X-FRAME-OPTIONS)
body: <p>I'm working with the dev version of Laravel (4.1.*) and there is a new default configuration that I don't want : <code>X-Frame-Options: SAMEORIGIN</code></p>
  
  <p>For the moment I disable it <a href="https://github.com/laravel/framework/blob/master/src/Illuminate/Http/FrameGuard.php#L40">by deleting one line in <code>Illuminate\Http\FrameGuard.php</code></a></p>
  
  <p>I'm looking for a better solution. I've try in the filtre.php file :</p>
  
  <pre><code>App::after(function($request, $response) {
     $response-&gt;header('X-Frame-Options', 'ALLOW-ALL');
  });
  </code></pre>
  
  <p>But it just adds the option (<code>X-Frame-Options:ALLOW-ALL, SAMEORIGIN</code>), whereas I need an override.</p>
