In the browser the response has this:
HTTP/1.0 200 OK
Date: Tue, 02 Jul 2013 22:53:47 GMT
Server: WSGIServer/0.1 Python/2.7.2
Vary: Cookie
Content-Type: text/plain
No content. But I verified from pdb that the python code is sending
something in the content when it does this:
return HttpResponse(content=data, content_type="text/plain", status=200)
