According to RFC 3986, both the scheme and host are case-insensitive. Therefore, this function normalizes both before constructing the pool key for an HTTPS request. If you wish to change this behaviour, provide alternate callables to ``key_fn_by_scheme``. :param key_class: The class to use when constructing the key. This should be a namedtuple with the ``scheme`` and ``host`` keys at a minimum. :type key_class: namedtuple :param request_context: A dictionary-like object that contain the context for a request. :type request_context: dict :return: A namedtuple that can be used as a connection pool key. :rtype: PoolKey t schemet hostt headerst _proxy_headerst _socks_optionst socket_optionst key_( R5 R6 R7 N( t copyt lowert Nonet frozensett itemst gett tuplet listt keyst popt _fields( t key_classt request_contextt contextt keyt socket_optst field( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_vendor/urllib3/poolmanager.pyt _default_key_normalizerJ s ! t httpt httpsc B@ s� e Z d Z d Z d d d � Z d � Z d � Z d d � Z d � Z d d d d � Z d � Z d d � Z d d � Z d � Z e d � Z RS( s$ Allows for arbitrary requests while transparently keeping track of necessary connection pools for you. :param num_pools: Number of connection pools to cache before discarding the least recently used pool. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param \**connection_pool_kw: Additional parameters are used to create fresh :class:`urllib3.connectionpool.ConnectionPool` instances.
