title: Ajax not working in IE11 error code 0x2f78
body: <p>Here is my ajax setup:</p>
  
  <pre><code>                $.support.cors = true;
                  $.ajax({
                      beforeSend: function ()
                      {
  
                      },
                      type: "POST",
                      url: "test.cgx",
                      data: hex_str,       
                      dataType: "xml",
                      processData: false,
                      contentType: "text/xml; charset=utf-8",
                      success: function (msg)
                      {
  
                      },
                      error: function (msg)
                      {
  
                      }
                  });
  </code></pre>
  
  <p>If the data - <code>hexstr</code> <strong>smaller than 4 chars</strong> (for example hex_str = "3A") I got the following error (after 1 minute of request pending):</p>
  
  <p><strong>XMLHttpRequest: Network Error 0x2f78, Could not complete the operation due to error 00002f78.</strong></p>
  
  <p>This happens only in IE, FF and Chrome can post any data size.
  The data I send it's not in XML format it's only Hex data (I need the  <code>contentType: "text/xml; charset=utf-8"</code>  for some other reason).  </p>
  
  <p>I'm using Jquery 1.8.2</p>
