In jQuery jqXhr, how can I access original xhr.getResponseHeader method?
<p>I have been beaten by this <a href="http://bugs.jquery.com/ticket/10338" rel="nofollow">bug</a> and I would like to work-around it by accessing <code>getResponseHeader</code> method of original xhr object and not the one provided in jqXhr which seems to use (broken) <code>getAllResponseHeaders</code>. Is there a way to access it? Without patching jQuery code itself?</p>

<p>Before upgrade to jQuery 1.7 I was using 1.4.2 and it worked. So I am assuming that using xhr's <code>getResponseHeader</code> directly will work.</p>
