Re: Django restframework based app on heroku showing error HTTP/1.1 505 HTTP Version Not Supported

Your HTTP Request is malformed. You have 2 spaces between the URI and
the HTTP version (rfc says only 1). Also, after your Content-Length
header you have an extra \r\n which will terminate the set of headers
and put the rest in the body.
