New submission from Stefano Mazzucco:
Hello,
at work, I am behind a proxy (squid) that is only available over http. So, I have to configure both the http_proxy and https_proxy environment variables to be something like "http://proxy.corp.com:8181"
Now, when I try and use urllib to open an "https" url, the proxy returns "501 Not Implemented".
The quick and dirty script below is a minimal demonstration of the problem that appears on both python 2.7 (tested on 2.7.6, 2.7.9, 2.7.10) and 3.4 (tested on 3.4.0 and 3.4.4)
try:
import urllib
opener = urllib.URLopener()
except AttributeError:
# Python 3
import urllib.request
opener = urllib.request.URLopener()
url = 'https://www.python.org'
print("Trying to open", url)
opener.open(url)
Changing the url to "http://" works OK.
Thanks,
-- Stefano
