The HTMLIFrameElement.referrerPolicy
property reflects the HTML referrerpolicy
attribute of the <iframe>
element defining which referrer is sent when fetching the resource.
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 (HTTPâHTTP, HTTPSâHTTPS), but isn't sent to a less secure destination (HTTPSâHTTP).
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 (HTTPSâHTTPS), but don't send it to a less secure destination (HTTPSâHTTP).
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 (HTTPSâHTTPS), and send no header to a less secure destination (HTTPSâHTTP).
unsafe-url
Send a full URL when performing a same-origin or cross-origin request.
Note: This policy will leak origins and paths from TLS-protected resources to insecure origins. Carefully consider the impact of this setting.
const iframe = document.createElement("iframe");
iframe.src = "/";
iframe.referrerPolicy = "unsafe-url";
const body = document.querySelector("body");
body.appendChild(iframe); // Fetch the image using the complete URL as the referrer
