"unknown protocol" error in httplib using HTTPS

[Manish Jethani]

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)
   con.set_debuglevel(1)
   con.request('GET',
     'https://nexus.passport.com:443/rdr/pprdr.asp')
   res = con.getresponse()
   print res.status, res.reason
   print res.read()

Here, "www-proxy" is the HTTPS proxy server that I have to go 
through (I can't connect directly). I'm trying to GET 
"https://nexus.passport.com:443/rdr/pprdr.asp" via the proxy, 
but I'm getting a "unknown protocol" error in return:

   File "test.py", line 9, in ?
     con.request('GET', 
'https://nexus.passport.com:443/rdr/pprdr.asp')
   File "c:\python23\lib\httplib.py", line 718, in request
     self._send_request(method, url, body, headers)
   File "c:\python23\lib\httplib.py", line 739, in _send_request
     self.endheaders()
   File "c:\python23\lib\httplib.py", line 712, in endheaders
     self._send_output()
   File "c:\python23\lib\httplib.py", line 597, in _send_output
     self.send(msg)
   File "c:\python23\lib\httplib.py", line 564, in send
     self.connect()
   File "c:\python23\lib\httplib.py", line 985, in connect 
ssl = socket.ssl(sock, self.key_file, self.cert_file)
   File "c:\python23\lib\socket.py", line 73, in ssl
     return _realssl(sock, keyfile, certfile) socket.sslerror: 
(1, 'error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown 
protocol')

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

Any help.

Thanks!

Manish
