I discovered that changing the URL to an https URL will not work on networks
using an older version of Squid, because of the way isenkram/urllib.urlopen()
handle https with proxies. urllib.urlopen() used by isenkram will try GET
https://... which Squid rejects. Using CONNECT ... instead work (which is
what wget/curl is doing). Perhaps isenkram need to use a different library
to fetch the https URL?
The same problem exist in unstable with the same old Squid proxy.
