Usage

Add Django HTTP Referrer Policy Middleware to your settings:

MIDDLEWARE = [
    ...
    'django_http_referrer_policy.middleware.ReferrerPolicyMiddleware',
    ...
]

Optional: provide variable REFERRER_POLICY to your settings with valid value if default value 'no-referrer-when-downgrade' does not suit to you:

REFERRER_POLICY = 'no-referrer'
