Since version 2.4.0 of requests, it is possible to specify a custom list
of socket options that need to be set before establishing the connection.
Example usage::
>>> import socket
>>> import requests
>>> from requests_toolbelt.adapters import socket_options
>>> s = requests.Session()
>>> opts = [(socket.IPPROTO_TCP, socket.TCP_NODELAY, 0)]
>>> adapter = socket_options.SocketOptionsAdapter(socket_options=opts)
>>> s.mount('http://', adapter)
You can also take advantage of the list of default options on this class
to keep using the original options in addition to your custom options. In
that case, ``opts`` might look like::
>>> opts = socket_options.SocketOptionsAdapter.default_options + opts
t default_socket_optionsi s� This version of Requests is only compatible with a version of urllib3 which is too old to support setting options on a socket. This adapter is functionally useless.c K s2 | j d | j � | _ t t | � j | � d S( Nt socket_options( t popt default_optionsR t superR t __init__( t selft kwargs( ( sM /usr/lib/python2.7/site-packages/requests_toolbelt/adapters/socket_options.pyR

The adapter sets 4 socket options:
- ``SOL_SOCKET`` ``SO_KEEPALIVE`` - This turns on TCP Keep-Alive
- ``IPPROTO_TCP`` ``TCP_KEEPINTVL`` 20 - Sets the keep alive interval
- ``IPPROTO_TCP`` ``TCP_KEEPCNT`` 5 - Sets the number of keep alive probes
- ``IPPROTO_TCP`` ``TCP_KEEPIDLE`` 60 - Sets the keep alive time if the
socket library has the ``TCP_KEEPIDLE`` constant
The latter three can be overridden by keyword arguments (respectively):
- ``idle``
- ``interval``
- ``count``
You can use this adapter like so::
>>> from requests_toolbelt.adapters import socket_options
>>> tcp = socket_options.TCPKeepAliveAdapter(idle=120, interval=10)
>>> s = requests.Session()
>>> s.mount('http://', tcp)
