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_optsfieldrTM/opt/hc_python/lib/python3.8/site-packages/pip/_vendor/urllib3/poolmanager.py_default_key_normalizerOs    rVhttphttpsc@seZdZdZdZdZd ddZddZdd Zd!d d Z d d Z d"ddZ ddZ d#ddZ d$ddZddZddZddZd%ddZdS)&ra$ 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.

In case of HTTP they are being sent with each request, while in the HTTPS/CONNECT case they are sent only once. Could be used for proxy authentication. :param proxy_ssl_context: The proxy SSL context is used to establish the TLS connection to the proxy when using HTTPS proxies. :param use_forwarding_for_https: (Defaults to False) If set to True will forward requests to the HTTPS proxy to be made on behalf of the client instead of creating a TLS tunnel via the CONNECT method. **Enabling this flag means that request and response headers and content will be visible from the HTTPS proxy** whereas tunneling keeps request and response headers and content private. IP address, target hostname, SNI, and port are always visible to an HTTPS proxy even when this flag is disabled.
