Request: referrerPolicy property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.
Note: This feature is available in Web Workers.
The referrerPolicy read-only property of the Request interface returns the referrer policy, which governs what referrer information, sent in the Referer header, should be included with the request.
Value
A string representing the request's referrerPolicy. For more information and possible values, see the Referrer-Policy HTTP header page.
Examples
In the following snippet, we create a new request using the Request() constructor (for an image file in the same directory as the script), then save the request referrer policy in a variable:
js
const myRequest = new Request("flowers.jpg"); const myReferrer = myRequest.referrerPolicy; // returns "" by default Specifications
