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 tdefault_socket_optionsicKs2|jd|jƒ|_tt|ƒj|dS(Ntsocket_options(tpoptdefault_optionsRtsuperRt__init__(tselftkwargs((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyR *s c Cs\tjdkr<tjd|d|d|d|jƒ|_ntt|ƒj|||ƒdS(Nit num_poolstmaxsizetblockR(trequestst __build__Rt PoolManagerRRRtinit_poolmanager(R t connectionsR R((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyR0s ( t__name__t __module__t__doc__tgetattrRtHTTPConnectiontsockett IPPROTO_TCPt TCP_NODELAYRR tFalseR(((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyR s tTCPKeepAliveAdaptercBseZdZd„ZRS(sJAn adapter for requests that turns on TCP Keep-Alive by default. 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) cKsâ|jdtjƒ}|jddƒ}|jddƒ}|jddƒ}|tjtjdftjtj|ftjtj|fg}t td dƒdk rÂ|tjtj |fg7}nt t |ƒjd||dS( NRtidlei<tintervalitcountiit TCP_KEEPIDLE(RRRRt SOL_SOCKETt SO_KEEPALIVERt TCP_KEEPINTVLt TCP_KEEPCNTRtNoneR!RRR (R R RRRR ((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyR Ys  (RRRR (((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyR?s( RRRRt_compatRRt HTTPAdapterRR(((sM/usr/lib/python2.7/dist-packages/requests_toolbelt/adapters/socket_options.pyts  3
