Module urllib

Functions that help access web URLs through proxy servers.

This module has two main user-facing functions:

get_opener - Returns a urllib2.OpenerDirector object that is configured to read proxy information from the Schrodinger configuration file. This OpenerDirector object also deals with tunnelling HTTPS proxy servers properly.
install_opener - Installs the urllib2.OpenerDirector object that would be returned by get_opener() as the default opener for all urllib2.urlopen calls.

geturl(): return the original request URL
code: HTTP status code
