OK.
I try pyopenssl and can get a secure socket to the server, but am
unsure how to use this socket with urllib2 or even httplib.
Here's the code I'm using:
import sys, socket, string, base64, httplib
from OpenSSL import SSL
# Connects to the server, through the proxy
def run(server, proxy):
After failed attempts at trying to get my code to work with squid.
I did some research into this and came up with some info.

- It would be nice if the built-in SSL socket type
could be used for non-blocking SSL I/O. Currently

That would be nice if something could be added to the distribution.
In general, what needs to be done is as follows:
#1: Connect to proxy host:port
#2: Send CONNECT request with host:443 of secure url you want to
tunnel to. Additional headers can be added depending on authorization
needed for
I am interested in any further progress with this, you may have made? I
am facing a similar issue. In short, I need to connect to a https site
(in this case a WSDL) that I need to access through an Http proxy. I
have tried various things to no avail. I did find a couple recipes on
the ASPN
Andrew,
It seems I'm not the only one going nuts here. I have just spent the
last 4 hrs stepping through the code in the debugger. It seems to get
stuck somewhere in the socket module (when it calls ssl) but haven't as
yet figured out exactly where.
I am _very_ interested to find that you have
Thanks for the update. I will/can keep you posted. I know for a fact we
use a Squid proxy which sounds like what you are using. I am going to
check out the faq you sent and see what it comes up with. I have also
been perusing the net a bit and looking at other client packages and see
if they
Hi!
HTTPS over a proxy (CONNECT) hasn't worked for a long time in python
(actually it has never worked).
A quick glance at the 2.4 Changelog doesn't suggest that this has been
fixed.
So basically you've got the following options:
a) redo your own http/https support.
b) look around on the net
Thanks for the feedback. andreas. I am looking into how to work my own
connection logic into the code. Google has quickly become my friend and
I am actually poking at cURL (pyCurl) to see what benefit it will be.
Thanks again.

If you need some help, send me an email and if we figure this out we
can post a resolution. I have used both approaches (having authored
them). Or at least let me know what site you are going to and I will
try them on a windows box and see if I can debug that the [EMAIL PROTECTED]@ is
going on.
Ideally, we should aim at a 'fix' that can be included in the
distribution. I am going to look at what communication goes on between
the proxy server and a working browser by monitoring the traffic. From
what i understand, the proxy needs to be told first to set up a secure
connection with the
Thanks Martin. That means my code should work.
I am trying to go through a proxy, which works fine for HTTP sites.
However, when I try a HTTPS site, the program doesn't respond for quite
a while, and returns the error:

Yes, on looking into it, sockets.ssl is not installed with
activepython, so it doesn't recognise https. So I have removed it, and
reinstalled the v 2.4.1 which I downloaded from www.python.org . This
leaves me with with the problem where the script 'hangs' for a long
time, then returns:
Following my above comment, if my script works with http, then what is
the problem with https, even when I change the ProxyHandler to specify
https?

I believe there is a bug in the https implementations of certain Web
services, in particular the Microsoft-ish ones. They are

The problem seems to lie with our company proxy (which requires

Hi all.
Some time ago (years) I had a script on Python 2.2 that would retieve a

and it worked wonderfully. I am revisiting the project and need to
update it to Python 2.4.1. python22-win32-ssl.zip isn't compatable
