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) >> > On Wed, Jul 3, 2013 at 12:06 AM, Larry Martell <[email protected]> >> > wrote: >> >> >> >> I'm invoking a view from an ajax call and I want to return data.
