About Referrer Policy

To allow other websites read the Referer request header when the visitors come there from a link on your website, set the Referrer Policy response header to origin. See other possible values.

The easiest way to do that is enabling the SecurityMiddleware and setting SECURE_REFERRER_POLICY:

MIDDLEWARE = [
    ...
    "django.middleware.security.SecurityMiddleware",
]

SECURE_REFERRER_POLICY = "origin"
