Middleware
==========

Custom Django middleware registered in
:doc:`/architecture/settings`.

disable_client_side_caching
---------------------------

Function-based middleware that adds ``never-cache`` headers
(``Cache-Control: max-age=0, no-cache, no-store, must-revalidate``,
``Expires: ...``, ``Pragma: no-cache``) to every response. Used to
guarantee that prices, transaction graphs and other rapidly-changing
data are never served from a stale browser cache.

Registered in ``MIDDLEWARE`` in :doc:`/architecture/settings`; it
sits at the tail of the stack, so it applies to every response that
makes it back out.
