title: Error code 12019 / 12007 ajax request on IE8
body: <p>If I disconnect my wifi before sending an ajax request on the IE 10 and FF, the request is aborted. The HTTP status code is 0 and response body is empty.</p>
  
  <p>On IE 8, the response code is 12007 or 12019 and response body is also empty.</p>
  
  <p>I have to have some error handling for aborted requests. </p>
  
  <p>Can I be sure that response code 12007 / 12019 corresponds to aborted request in IE8? Or can it be sent back for other errors? </p>
  
  <p>I see from <a href="http://support.microsoft.com/kb/193625" rel="noreferrer">MS doc</a> that this error means:</p>
  
  <pre><code>   12019       ERROR_INTERNET_INCORRECT_HANDLE_STATE
                 The requested operation cannot be carried out because the
                 handle supplied is not in the correct state.
  
     12007       ERROR_INTERNET_NAME_NOT_RESOLVED
                 The server name could not be resolved.
  </code></pre>
  
  <p>I just want to be sure that I am correct in thinking that this error is only likely happen when there is n/w failure of some sort.</p>
