did this a long time ago when behind a corporate proxy server worked
then might be a start for you
I am fuzzy on the details.

import httplib
import base64
import getpass
def getWebPage(userName='YourUserName',httpPage='http://
weather.noaa.gov/weather/current/KRIC.html',outFilePath=None):
    # 1. connect to the proxy
    h1 = httplib.HTTP("proxyconf",)

    # 2. give the absolute URL in the request
    h1.putrequest('GET', 'http://weather.noaa.gov/weather/current/
KRIC.html')

    h1.putheader('Accept', 'text/html')
    h1.putheader('Accept', 'text/plain')
    password = getpass.getpass()
    # 3. set the header with a base64 encoding of user-id:passwd
    userString = "%s:%s" % (userName,password)
    auth = "Basic " + base64.encodestring(userString)
    h1.putheader('Proxy-Authorization', auth)
    h1.endheaders()

    # 4. get the page
    errcode, errmsg, headers = h1.getreply()

    print errcode
    print errmsg
    print headers

    f=h1.getfile()
    if(not outFilePath):
        for line in f.readlines():
            print line
    else:
        try:
            outFile = open(outFilePath,'w')
            # yada yaha
