title: Access control for cross site requests in Internet Explorer
body: <p>I am trying to make an AJAX call from several domains to a single one which will handle the request. Enabling Cross domain in Firefox and Chrome was easy by setting the header on the handling server:</p>
  
  <pre><code>header("Access-Control-Allow-Origin: *");
  </code></pre>
  
  <p>But this doesn't help enabling it in Internet Explorer. When I try:</p>
  
  <pre><code>httpreq.send('');
  </code></pre>
  
  <p>it stops with error Access denied.</p>
  
  <p>How can this be enabled in Internet Explorer?</p>
