"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!
