I'm using Python 2.3.3 to do HTTPS using the httplib module.
Here's the code:

from httplib import HTTPSConnection
con = HTTPSConnection('www-proxy', 80)
res = con.getresponse()
print res.status, res.reason

Here, "www-proxy" is the HTTPS proxy server that I have to go
through (I can't connect directly). I'm trying to GET
"" via the proxy,
but I'm getting a "unknown protocol" error in return:

File "", line 9, in ?
File "c:\python23\lib\", line 718, in request
self._send_request(method, url, body, headers)
File "c:\python23\lib\", line 739, in _send_request
File "c:\python23\lib\", line 712, in endheaders
File "c:\python23\lib\", line 597, in _send_output
File "c:\python23\lib\", line 564, in send
File "c:\python23\lib\", line 985, in connect
ssl = socket.ssl(sock, self.key_file, self.cert_file)
File "c:\python23\lib\", line 73, in ssl
return _realssl(sock, keyfile, certfile) socket.sslerror:
(1, 'error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown

What's the problem here? I just want to use SSL over my HTTPS
proxy using httplib.

Any help.
