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 schemehost)headers_proxy_headers_socks_optionsNsocket_optionskey_) copylower frozensetitemsgettuplelistkeyspop_fields) key_classrequest_contextcontextkey socket_optsfieldrLC/tmp/pip-unpacked-wheel-hu9qqap1/pip/_vendor/urllib3/poolmanager.py_default_key_normalizerDs     rN)httphttpsc@sxeZdZdZdZdddZddZdd Zdd d Zd d Z dddZ ddZ dddZ d ddZ ddZd!ddZdS)"ra$ 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.
