If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. 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. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry.

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.

If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. 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. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry.

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.

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.
