Check the Browser compatibility table carefully before using this in production.
The HTMLAreaElement.referrerPolicy property reflect the HTML referrerpolicy attribute of the <area> element defining which referrer is sent when fetching the resource.
A DOMString; one of the following:
The Referer header will be omitted entirely. No referrer information is sent along with requests.
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).
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/.
Send a full URL when performing a same-origin request, but only send the origin of the document for other cases.
A referrer will be sent for same-site origins, but cross-origin requests will contain no referrer information.
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).
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).
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.
