ReferrerPolicy enum

Values

default_ → const ReferrerPolicy

const ReferrerPolicy('')

noReferrer → const ReferrerPolicy

The Referer header will be omitted: sent requests do not include any referrer information.

const ReferrerPolicy('no-referrer')

noReferrerWhenDowngrade → const ReferrerPolicy

Send the origin, path, and querystring in Referer when the protocol security level stays the same or improves (HTTP→HTTP, HTTP→HTTPS, HTTPS→HTTPS). Don't send the Referer header for requests to less secure destinations (HTTPS→HTTP, HTTPS→file).

const ReferrerPolicy('no-referrer-when-downgrade')

origin → const ReferrerPolicy

Send only the origin in the Referer header. For example, a document at https://example.com/page.html will send the referrer https://example.com/.

const ReferrerPolicy('origin')

originWhenCrossOrigin → const ReferrerPolicy

When performing a same-origin request to the same protocol level (HTTP→HTTP, HTTPS→HTTPS), send the origin, path, and query string. Send only the origin for cross origin requests and requests to less secure destinations (HTTPS→HTTP).

const ReferrerPolicy('origin-when-cross-origin')

sameOrigin → const ReferrerPolicy

Send the origin, path, and query string for same-origin requests. Don't send the Referer header for cross-origin requests.

const ReferrerPolicy('same-origin')

strictOrigin → const ReferrerPolicy

Send only the origin when the protocol security level stays the same (HTTPS→HTTPS). Don't send the Referer header to less secure destinations (HTTPS→HTTP).

const ReferrerPolicy('strict-origin')

strictOriginWhenCrossOrigin → const ReferrerPolicy

Send the origin, path, and querystring when performing a same-origin request. For cross-origin requests send the origin (only) when the protocol security level stays same (HTTPS→HTTPS). Don't send the Referer header to less secure destinations (HTTPS→HTTP).

const ReferrerPolicy('strict-origin-when-cross-origin')

unsafeUrl → const ReferrerPolicy

Send the origin, path, and query string when performing any request, regardless of security.

const ReferrerPolicy('unsafe-url')
