| AXES_ENABLE_RETRY_AFTER_HEADER | False | If ``True``, ``AxesMiddleware`` sets the ``Retry-After`` HTTP header on lockout responses when ``AXES_COOLOFF_TIME`` is configured. Set to ``False`` to disable this header. |

| AXES_LOCKOUT_PARAMETERS | ["ip_address"] | A list of parameters that Axes uses to lock out users. It can also be callable, which takes an http request or AccesAttempt object and credentials and returns a list of parameters. Each parameter can be a string (a single parameter) or a list of strings (a combined parameter). For example, if you configure ``AXES_LOCKOUT_PARAMETERS = ["ip_address", ["username", "user_agent"]]``, axes will block clients by ip and/or username and user agent combination. See :ref:`customizing-lockout-parameters` for more details. |

.. note::
If ``AXES_ENABLE_RETRY_AFTER_HEADER`` is enabled and ``AXES_COOLOFF_TIME`` is configured,
``AxesMiddleware`` adds a ``Retry-After`` HTTP header (`RFC 7231 <https://datatracker.ietf.org/doc/html/rfc7231#section-7.1.3>`_)
with the cool-off duration in seconds. This header is not added for redirects
(``AXES_LOCKOUT_URL``) or custom lockout responses (``AXES_LOCKOUT_CALLABLE``).
The configuration option precedences for the access attempt monitoring are:
1. Default: only use IP address.
