Set a valid Referrer-Policy on Cloudflare
Why it matters
The Referrer-Policy value is not one browsers recognise, so they ignore it and use their own default. Use a standard value such as strict-origin-when-cross-origin.
The fix
- Create or edit a Response Header Transform Rule (Rules, Overview) with Set static, header Referrer-Policy, value strict-origin-when-cross-origin. Set replaces the origin's value.
