title: Firefox responds to php header() with blank page (while chrome behaves as expected)
body: <p>So I have a php page that only accepts POST method from another script coming from same host. Anything else I want to respond with</p>
  
  <pre><code>    header("HTTP/1.1 403");
  </code></pre>
  
  <p>With chrome, I get a :( page saying access denied.  IE also shows a similar error page. With firefox, I just get an empty page. I made a php script with just that line above and the result is the same.</p>
  
  <p>Am I doing something wrong or is firefox just quirky.</p>
