Can't get shared-contacts.py to work through a proxy server

[GoogleCodeExporter]

What steps will reproduce the problem?
1. behind proxy server (BlueCoat) set to not autenticate
2. set http_proxy=http://fqdn:80/ and set https_proxy=http://fqdn:80/
3. shared-contacts.py -a username@domain -p pass -e out.csv

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
windows server 2003 R2 SP2
python 2.5.4 or python 2.4.4
gdata 1.3.1
shared-contacts 1.0.1

Please provide any additional information below.

python 2.6 gives a different error behind proxy. I can run the same command
on a Windows XP system at home (not behind the proxy)

To use the Python script for shared contacts behind a proxy, you would need to 
edit
the file 'shared_contacts.py' and include the following with your network 
settings:

import os

os.environ['http_proxy'] = 'http://192.168.1.2:1234' 
os.environ['https_proxy'] = 'https://192.168.1.2:1234' 
os.environ['proxy-username'] = 'user' 
os.environ['proxy-password'] = 'pass'

FYI, passing the no-cache option with the connection resolves this for us 
(NOTE: we
are using BlueCoat proxy appliances).

Here is the response from Google with the details:

Hi Edward,

I think your proxy server is sending an invalid value for the header
'max-stale' to the Google server, what kind of proxy server are you using?

Maybe you could try to set 'no-cache' or send a valid value for
'max-stale', you can add additional headers on the contacts_service class
constructor, for example:

 contacts_service = gdata.contacts.service.ContactsService(
     email = admin_email,
     password = admin_password,
     account_type = 'HOSTED',
     contact_list = domain,
     source = 'shared_contacts',
     additional_headers = {'Cache-Control':'no-cache'},
   )

For the next version can the no-cache be made a configurable option for this 
script
(command line switch or env variable or config file or something)?
Thanks,
Ed
