Description
After combining django and twisted using the twisted.web.wsgi module I wasn't able to retrieve any POST parameter passed from the browser.
After some debugging I got to the twisted.wsgi._WSGIResponse there the "wsgi.input" parameter was initialized to a cStringIO object which was positioned to the end of the stream, and thus any call to the read method returned an empty string. That effectively prevented django or any other framework to extract the content of the stream and parse the POST parameters.
I have added a workaround consisting on performing a request.content.seek(0) to rewind the cStringIO object and allow the django request to correctly retrieve the post parameters.
