Referrer-Policy stripping referrer information
Referrer-Policy.*no-referrer|Referer header.*stripped|referrer.*not sent
Fixes
- 1.Set Referrer-Policy: strict-origin-when-cross-origin for a balance of privacy and functionality
- 2.Use no-referrer-when-downgrade if you need the full URL sent to same-protocol destinations
- 3.For analytics that depend on referrer, ensure the policy permits it for same-origin requests
