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 int max_retries: The maximum number of retries each connection should attempt. Note, this applies only to failed connections and timeouts, never to requests where the server returns a response. :param pool_block: Whether the connection pool should block for connections.
