What is Referrer-Policy?
Referrer-Policy controls how much of the URL a browser includes in the Referer header on navigation and resource requests. Safer policies reduce leakage of paths, queries, and secrets.
Recommended values
- strict-origin-when-cross-origin (modern default, balanced)
- no-referrer (maximum privacy for sensitive apps)
Tool-specific questions
Is no-referrer always best?
Do I need both meta and header?
