Background:

https://github.com/phuslu/requests_httpsproxy
Issue:
ssl module(python 2.7) counld establish ssl handshakes over a https-proxy
Reproduce Steps:

>>> import socket,ssl
>>> sock = ssl.wrap_socket(socket.create_connection(('bwg.phus.lu', 443)))
>>> sock.sendall('CONNECT httpbin.org:443 HTTP/1.0\r\n\r\n')
36
>>> sock.recv()
'HTTP/1.1 200 OK\r\n\r\n'
>>> ssl.wrap_socket(sock)
Traceback (most recent call last):
