HTMLLinkElement.referrerPolicy

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTMLLinkElement.referrerPolicy property reflect the HTML referrerpolicy attribute of the <link> element defining which referrer is sent when fetching the resource.

See the HTTP Referrer-Policy header for details.

Value

A DOMString; one of the following:

no-referrer

The Referer header will be omitted entirely. No referrer information is sent along with requests.

no-referrer-when-downgrade

The URL is sent as a referrer when the protocol security level stays the same (e.g.HTTP→HTTP, HTTPS→HTTPS), but isn't sent to a less secure destination (e.g. HTTPS→HTTP).

origin

Only send the origin of the document as the referrer in all cases. The document https://example.com/page.html will send the referrer https://example.com/.

origin-when-cross-origin

Send a full URL when performing a same-origin request, but only send the origin of the document for other cases.

same-origin

A referrer will be sent for same-site origins, but cross-origin requests will contain no referrer information.

strict-origin

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 (default)

This is the user agent's default behavior if no policy is specified. Send a full URL when performing a same-origin request, 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

Send a full URL when performing a same-origin or cross-origin request. This policy will leak origins and paths from TLS-protected resources to insecure origins. Carefully consider the impact of this setting.

Examples

var links = document.getElementsByTagName("link");
links[0].referrerPolicy; // "no-referrer"
