django-beefycachecontrol

django-beefycachecontrol

django-beefycachecontrol is a Django middleware that smacks misbehaving upstream caches into submission with beefier anti-cache HTTP headers.

Normally, when a view is decorated with @never_cache::

@never_cache
def my_view(request):
    ...

The resulting HTTP headers (among other things) include::

Cache-Control	max-age=0

While this should be sufficient to prevent the response from being cached upstream, but there may be circumstances where this is not enough. Enter django-beefiercachecontrol!

With BeefyCacheControlMiddleware enabled, these HTTP headers become::

Cache-Control	max-age=0, no-cache, no-store

Cache that and you'd be arrested by the internet cops!
