Backwards-compatible to httplib's HTTPResponse but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in httplib.HTTPResponse: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, attempts to decode specific content-encoding's based on headers (like 'gzip' and 'deflate') will be skipped and raw data will be used instead. :param original_response: When this HTTPResponse wrapper is generated from an httplib.HTTPResponse object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present. Otherwise, raise error.
