Hi,

I'am working on enhancing keystone PublicAPI to support CORS.
Everything seem to work well except that Keystone is formatting
responses with Transfer-Encoding: chunked which isn't accepted for
OPTIONS query by browsers (chrome, firefox). Does anyone knows how to
force keystone API to use plain format ? My CorsController is as
follows:


class CorsController(wsgi.Application):
    def __init__(self):
        super(CorsController, self).__init__()
    def get_options(self, context):
        headers = [('Access-Control-Allow-Headers',
'origin,content-type,accept,x-auth-token')]
        headers.append(('Access-Control-Allow-Methods', 'POST'))
        headers.append(('Access-Control-Allow-Origin',
'https://178.239.138.10:8433'))
        headers.append(('Access-Control-Max-Age', '60'))
        headers.append(('Content-Length', '0'))
        return wsgi.render_response(status=(200, 'OK'),
                                    headers=headers)


Sample request:

 echo -e 'OPTIONS /v2.0/tokens HTTP/1.1\r\n' | nc 10.76.0.119 5000
HTTP/1.1 200 OK
Access-Control-Allow-Headers: origin,content-type,accept,x-auth-token
Access-Control-Allow-Methods: POST
Access-Control-Allow-Origin: https://10.76.0.119:8433
Access-Control-Max-Age: 60
Date: Thu, 21 Jun 2012 16:52:33 GMT
Transfer-Encoding: chunked
