Constants
- NO_REFERRER → const ReferrerPolicy
- The Referer header will not be sent.
- NO_REFERRER_WHEN_DOWNGRADE → const ReferrerPolicy
- The Referer header will not be sent to origins without TLS (HTTPS).
- ORIGIN → const ReferrerPolicy
- The sent referrer will be limited to the origin of the referring page: its scheme, host, and port.
- ORIGIN_WHEN_CROSS_ORIGIN → const ReferrerPolicy
- The referrer sent to other origins will be limited to the scheme, the host, and the port. Navigations on the same origin will still include the path.
- SAME_ORIGIN → const ReferrerPolicy
- A referrer will be sent for same origin, but cross-origin requests will contain no referrer information.
- STRICT_ORIGIN → const ReferrerPolicy
- Only send the origin of the document as the referrer when the protocol security level stays the same (e.g. HTTPS -> HTTPS), but don't send it to a less secure destination (e.g. HTTPS -> HTTP).
- STRICT_ORIGIN_WHEN_CROSS_ORIGIN → const ReferrerPolicy
- Send a full URL when performing a same-origin request, but only send the origin when the protocol security level stays the same (e.g.HTTPS -> HTTPS), and send no header to a less secure destination (e.g. HTTPS -> HTTP).
- UNSAFE_URL → const ReferrerPolicy
- The referrer will include the origin and the path (but not the fragment, password, or username). This value is unsafe, because it leaks origins and paths from TLS-protected resources to insecure origins.
