Django disable cache headers

Middleware that disables caching headers during development in Django.

In production you will typically a CDN or browser cache to speed up subsequent reads of your pages. This ensures reads don't need to hit your DB as often.

from django.views.decorators.cache import cache_control

@method_decorator(cache_control(public=True, max_age=60 * 5)), name="dispatch")
def my_view(request):
    ...

However this is annoying during development as you always want to serve fresh pages and static files on page refresh. Using this middleware in development strips out the cache headers and prevents the browser (or dev cache) from caching your content.

Quickstart

Install Django disable cache headers:

pip install django-disable-cache-headers

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'disable_cache_headers.apps.DisableCacheHeadersConfig',
    ...
)

Add the middleware in your development settings, e.g in config/settings/local.py.

from .base import *
MIDDLEWARE += ["disable_cache_headers.middleware.DisableCacheControl"]
