-'''SSL with SNI_-support for Python 2.
-
-This needs the following packages installed:
-
-* pyOpenSSL (tested with 0.13)
-* ndg-httpsclient (tested with 0.3.2)
-* pyasn1 (tested with 0.1.6)
-
-To activate it call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3`.
-This can be done in a ``sitecustomize`` module, or at any other time before
-your application begins using ``urllib3``, like this::
-
-    try:
-        import urllib3.contrib.pyopenssl
-        urllib3.contrib.pyopenssl.inject_into_urllib3()
-    except ImportError:
-        pass
-
-Now you can use :mod:`urllib3` as you normally would, and it will support SNI
-when the required modules are installed.
-
-Activating this module also has the positive side effect of disabling SSL/TLS
-encryption in Python 2 (see `CRIME attack`_).
-
-If you want to configure the default list of supported cipher suites, you can
-set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

-    Utility object for storing timeout values.

-        timeout = urllib3.util.Timeout(connect=2.0, read=7.0)

-        The maximum amount of time to wait for a connection attempt to a server
-        to succeed. Omitting the parameter will default the connect timeout to
-        the system default, probably `the global default timeout in socket.py
-        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
-        None will set an infinite timeout for connection attempts.
-
-    :type connect: integer, float, or None
-
-    :param read:
-        The maximum amount of time to wait between consecutive
-        read operations for a response from the server. Omitting
-        the parameter will default the read timeout to the system
-        default, probably `the global default timeout in socket.py
-        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
-        None will set an infinite timeout.
-
-    :type read: integer, float, or None
-
-    :param total:
-        This combines the connect and read timeouts into one; the read timeout
-        will be set to the time leftover from the connect attempt. In the
-        event that both a connect timeout and a total are specified, or a read
-        timeout and a total are specified, the shorter timeout will be applied.
-
-        Defaults to None.
-
-    :type total: integer, float, or None
-
-    .. note::
-
-        Many factors can affect the total amount of time for urllib3 to return
-        an HTTP response. Specifically, Python's DNS resolver does not obey the
-        timeout specified on the socket. Other factors that can affect total
-        request time include high CPU load, high swap, the program running at a
-        low priority level, or other behaviors. The observed running time for
-        urllib3 to return a response may be greater than the value passed to
-        `total`.
-
-        In addition, the read and total timeouts only measure the time between
-        read operations on the socket connecting the client and the server,
-        not the total amount of time for the request to return a complete
-        response. For most requests, the timeout is raised because the server
-        has not sent the first byte in the specified time. This is not always
-        the case; if a server streams one byte every fifteen seconds, a timeout
-        of 20 seconds will not ever trigger, even though the request will
-        take several minutes to complete.
-
-        If your goal is to cut off any request after a set amount of wall clock
-        time, consider having a second "watcher" thread to cut off a slow
-        request.
