title: Emulate a 403 error page
body: <p>I know you can send a header that tells the browser this page is forbidden like:</p>
  
  <pre><code>header('HTTP/1.0 403 Forbidden');
  </code></pre>
  
  <p>But how can I also display the custom error page that has been created on the server for this type of error?</p>
  
  <p>By default, just sending the header displays a white page, but I remember a while back reading that you can use the customer error page. Does anybody know?</p>
