title: Remove http referer host and other info about site in ajax-requests
body: <p>Is there any way to remove referer or host or other information of the current site when doing an ajax-request?</p>
  
  <p>This is what I've tried so far with jQuery:</p>
  
  <pre><code>$.ajax({
      type: "POST",
      url: $.appData.edit_item_ajax_url,
      data: ajax_params,
      beforeSend: function(jqXHR, settings) {
          jqXHR.setRequestHeader('Host', 'This gets owerwritten');
          jqXHR.setRequestHeader('Referer', 'This gets owerwritten');
          jqXHR.setRequestHeader('Test-param', 'This is fine...');
      }
  }).done(function( msg ) {
      debug( "Data Saved: " + msg );
  });
  </code></pre>
  
  <p>But sadly, it does not work. </p>
