-------------------------------
Default: ``False``
.. deprecated:: 1.6
This setting was largely ineffective because of using cookies for sessions
and CSRF. See the :doc:`Django 1.6 release notes</releases/1.6>` for more
information.
If the value of this setting is ``True``, only anonymous requests (i.e., not
those made by a logged-in user) will be cached. Otherwise, the middleware
caches every page that doesn't have GET or POST parameters.
If you set the value of this setting to ``True``, you should make sure you've
activated ``AuthenticationMiddleware``.
