So your TurboGears application accesses resources on other servers?

Just define your own config setting and then in your controller code or in your
start script do something like the following:
import os
if turbogears.config.get('http_proxy'):
os.environ['http_proxy'] = turbogears.config.get('http_proxy')
import urllib
Test (with local Squid proxy):
>>> r = urllib.urlopen('http://docs.python.org/lib/module-urllib.html')
>>>r.headers.items()
[('content-length', '28486'),
('proxy-connection', 'close'),
('x-cache', 'HIT from musicbox.paddyland.lan'),
('accept-ranges', 'bytes'),
('server',
'Apache/2.0.54 (Debian GNU/Linux) DAV/2 SVN/1.1.4 mod_python/3.1.3
Python/2.3.5 mod_ssl/2.0.54 OpenSSL/0.9.7e'),

('age', '358')]
Just be sure to import urllib after you have set the environment variable. Also
note that this does not work on Windows. See the urllib doc for more.
