I have set up CSRF as described in the Django docs (using Django 1.3). It works with FF and Safari, but on IE9 I get
<div id="summary">
<h1>Forbidden <span>(403)</span></h1>
<p>CSRF verification failed. Request aborted.</p>
</div>
In the response headers of the Ajax request I find
Set-Cookie csrftoken=8db3637951243ffb591e6b2d6998ed03; expires=Fri, 14-Sep-2012 08:01:52 GMT; Max-Age=31449600; Path=/
It works in IE9 when using it in a normal Form (i.e. no Ajax involved).
I am using Django behind nginx/1.1.2.
Any hints what I am missing here?
