referrer-policy

Express/Connect middleware to set the Referrer-Policy HTTP header, part of the Helmet.js security suite. Version 1.2.0 is stable and works with Node >=4. Ships TypeScript definitions. Allows specifying one of the standard policy values (e.g., no-referrer, same-origin, strict-origin-when-cross-origin) or an array of policies for fallback. Lightweight and focused, with no external dependencies.
