If ``None`` (default) will retry 3 times, see ``Retry.DEFAULT``. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries.

This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``preload_content`` which defaults to ``True``. :param bool chunked: If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False. :param int body_pos: Position to seek to in file-like body in the event of a retry or redirect.
