Best Practices

1. Start with strict policies and relax only when necessary
2. Use same-origin for sensitive areas like admin panels
3. Implement no-referrer for password reset and payment pages
4. Test thoroughly with analytics and third-party services
5. Document your policy choices for team understanding
6. Monitor referrer data to ensure policies work as expected
7. Consider user privacy preferences in policy selection
8. Use HTML-level controls for fine-grained management

The Referrer-Policy header provides essential control over information leakage, balancing security and privacy needs with functional requirements like analytics and partner integrations. By implementing appropriate policies, organizations can protect sensitive URL information while maintaining necessary functionality. As privacy regulations continue to evolve, proper referrer policy implementation becomes not just a security best practice but a compliance requirement.## Permissions-Policy: Managing Browser Features

The Permissions-Policy header (formerly Feature-Policy) provides granular control over which browser features and APIs can be used by your website and embedded content. This powerful security mechanism helps prevent privacy violations, reduces attack surface, and ensures that powerful browser capabilities are only used when explicitly intended. As web browsers continue to add new APIs for accessing device capabilities, Permissions-Policy becomes increasingly critical for maintaining security and user privacy.
