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
