Middleware to work around #30862

Chrome started rolling out changes that brake Django sites with intentionally empty SameSite cookie settings.

This middleware sets the value "None" on those cookies explicitly. Also sets Secure to True for all altered cookies.

Installation

Get it from PyPi:

pip install django-samesite-none

Put it first in the MIDDLEWARE list in your settings.py:

MIDDLEWARE = [
    "django_samesite_none.middleware.SameSiteNoneMiddleware",
    ...
]
