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 �scheme�host)�headers�_proxy_headersZ_socks_optionsNZsocket_optionsZkey_) �copy�lower� frozenset�items�get�tuple�list�keys�pop�_fields)Z key_class�request_context�context�keyZ socket_optsZfield� r% �C/usr/lib/python3.8/site-packages/pip/_vendor/urllib3/poolmanager.py�_default_key_normalizerD s r' ��http�httpsc @ sx e Zd ZdZdZd dd�Zdd� Zdd � Zd d d �Zd d � Z d dd�Z dd� Z d dd�Z d dd�Z dd� Zd!dd�ZdS )"r a$ 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.
