+If a view sets its own cache expiry time (i.e. it has a ``max-age`` section in
+its ``Cache-Control`` header) then the page will be cached until the expiry
+time, rather than ``CACHE_MIDDLEWARE_SECONDS``. Using the decorators in
+``django.views.decorators.cache`` you can easily set a view's expiry time
+(using the ``cache_control`` decorator) or disable caching for a view (using
+the ``never_cache`` decorator). See the `using other headers`__ section for
+more on these decorators.
