httpHandler = urllib2.HTTPHandler(debuglevel=1)
httpsHandler = urllib2.HTTPSHandler(debuglevel=1)
opener = urllib2.build_opener(httpHandler, httpsHandler)
urllib2.install_opener(opener)
headers = {

request = urllib2.Request(url, None, headers)
response = urllib2.urlopen(request)
page = response.read()

print page
