The simplest way to use this module is to call the urlopen function,
which accepts a string containing a URL or a Request object (described
below).  It opens the URL and returns the results as file-like
object; the returned object has some extra methods described below.

The OpenerDirector manages a collection of Handler objects that do
all the actual work.  Each Handler implements a particular protocol or
option.  The OpenerDirector is a composite object that invokes the
Handlers needed to open the requested URL.  For example, the
HTTPHandler performs HTTP GET and POST requests and deals with
non-error returns.  The HTTPRedirectHandler automatically deals with
HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler
deals with digest authentication.

urlopen(url, data=None) -- Basic usage is the same as original
urllib.  pass the url and optionally data to post to an HTTP URL, and
get a file-like object back.  One difference is that you can also pass
a Request instance instead of URL.  Raises a URLError (subclass of
IOError); for HTTP errors, raises an HTTPError, which can also be
treated as a valid response.

build_opener -- Function that creates a new OpenerDirector instance.
Will install the default handlers.  Accepts one or more Handlers as
arguments, either instances or Handler classes that it will
instantiate.  If one of the argument is a subclass of the default
handler, the argument will be installed instead of the default.

install_opener -- Installs a new opener as the default opener.

objects of interest:

OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages
the Handler classes, while dealing with requests and responses.

Request -- An object that encapsulates the state of a request.  The
state can be as simple as the URL.  It can also include extra HTTP
headers, e.g. a User-Agent.

BaseHandler --

exceptions:
URLError -- A subclass of IOError, individual protocols have their own
specific subclass.

HTTPError -- Also a valid HTTP response, so you can treat an HTTP error
as an exceptional event or valid response.

internals:
BaseHandler and parent
_call_chain conventions

Example usage:

import urllib2

# set up authentication info
authinfo = urllib2.HTTPBasicAuthHandler()
authinfo.add_password(realm='PDQ Application',
                      uri='https://mahler:8092/site-updates.py',
                      user='klem',
                      passwd='geheim$parole')

proxy_support = urllib2.ProxyHandler({"http" : "http://ahad-haam:3128"})

# build a new opener that adds authentication and caching FTP handlers
opener = urllib2.build_opener(proxy_support, authinfo, urllib2.CacheFTPHandler)

# install it
urllib2.install_opener(opener)

f = urllib2.urlopen('http://www.python.org/')

d}}||||fS(s3Return (scheme, user, password, host/port) given a URL or an authority.

    If a URL is supplied, it must have an authority (host:port) component.
    According to RFC 3986, having an authority component means the URL must
    have two slashes after the scheme:

    >>> _parse_proxy('file:/ftp.example.com/')
    Traceback (most recent call last):
    ValueError: proxy URL with no authority: 'file:/ftp.example.com/'

    The first three items of the returned tuple may be None.

    Examples of authority parsing:

    >>> _parse_proxy('proxy.example.com')
    (None, None, None, 'proxy.example.com')
    >>> _parse_proxy('proxy.example.com:3128')
    (None, None, None, 'proxy.example.com:3128')

    The authority component may optionally include userinfo (assumed to be
    username:password):

    >>> _parse_proxy('joe:password@proxy.example.com')
    (None, 'joe', 'password', 'proxy.example.com')
    >>> _parse_proxy('joe:password@proxy.example.com:3128')
    (None, 'joe', 'password', 'proxy.example.com:3128')

    Same examples, but with URLs instead:

    >>> _parse_proxy('http://proxy.example.com/')
    ('http', None, None, 'proxy.example.com')
    >>> _parse_proxy('http://proxy.example.com:3128/')
    ('http', None, None, 'proxy.example.com:3128')
    >>> _parse_proxy('http://joe:password@proxy.example.com/')
    ('http', 'joe', 'password', 'proxy.example.com')
    >>> _parse_proxy('http://joe:password@proxy.example.com:3128')
    ('http', 'joe', 'password', 'proxy.example.com:3128')

    Everything after the authority is ignored:

    >>> _parse_proxy('ftp://joe:password@proxy.example.com/rubbish:3128')
    ('ftp', 'joe', 'password', 'proxy.example.com')

    Test for no trailing '/' case:

    >>> _parse_proxy('http://joe:password@proxy.example.com')
    ('http', 'joe', 'password', 'proxy.example.com')
