Provides a general-case interface for Requests sessions to contact HTTP and
HTTPS urls by implementing the Transport Adapter interface. This class will
usually be created by the :class:`Session <Session>` class under the
covers.
:param pool_connections: The number of urllib3 connection pools to cache.
:param pool_maxsize: The maximum number of connections to save in the pool.
:param max_retries: The maximum number of retries each connection
should attempt. Note, this applies only to failed DNS lookups, socket
connections and connection timeouts, never to requests where data has
made it to the server. By default, Requests does not retry failed
connections. If you need granular control over the conditions under
which we retry a request, import urllib3's ``Retry`` class and pass
that instead.
:param pool_block: Whether the connection pool should block for connections.
Usage::
>>> import requests
>>> s = requests.Session()
>>> a = requests.adapters.HTTPAdapter(max_retries=3)
>>> s.mount('http://', a)

This looks at the PreparedRequest, the user-specified verify value,
and the value of the cert parameter to determine what PoolKey values
to use to select a connection from a given urllib3 Connection Pool.
The SSL related pool key arguments are not consistently set. As of
this writing, use the following to determine what keys may be in that
dictionary:
* If ``verify`` is ``True``, ``"ssl_context"`` will be set and will be the
default Requests SSL Context
* If ``verify`` is ``False``, ``"ssl_context"`` will not be set but
``"cert_reqs"`` will be set
* If ``verify`` is a string, (i.e., it is a user-specified trust bundle)
``"ca_certs"`` will be set if the string is not a directory recognized
by :py:func:`os.path.isdir`, otherwise ``"ca_cert_dir"`` will be
set.
* If ``"cert"`` is specified, ``"cert_file"`` will always be set. If
``"cert"`` is a tuple with a second item, ``"key_file"`` will also
be present
To override these settings, one may subclass this class, call this
method and use the above logic to change parameters as desired. For
example, if one wishes to use a custom :py:class:`ssl.SSLContext` one
must both set ``"ssl_context"`` and based on what else they require,
alter the other keys to ensure the desired behaviour.
:param request:
The PreparedReqest being sent over the connection.
:type request:
:class:`~requests.models.PreparedRequest`
:param verify:
Either a boolean, in which case it controls whether
we verify the server's TLS certificate, or a string, in which case it
must be a path to a CA bundle to use.
:param cert:
(optional) Any user-provided SSL certificate for client
authentication (a.k.a., mTLS). This may be a string (i.e., just
the path to a file which holds both certificate and key) or a
tuple of length 2 with the certificate file path and key file
path.
:returns:
A tuple of two dictionaries. The first is the "host parameters"
portion of the Pool Key including scheme, hostname, and port. The
second is a dictionary of SSLContext related parameters.
