Request.referrerPolicy

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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.

Syntax

var myReferrerPolicy = request.referrerPolicy;

Value

A DOMString representing the request's referrerPolicy. For more information and possible values, see the Referrer-Policy HTTP header page.

Example

In the following snippet, we create a new request using the Request.Request() constructor (for an image file in the same directory as the script), then save the request referrer policy in a variable:

var myRequest = new Request('flowers.jpg');
var myReferrer = myRequest.referrerPolicy; // returns "" by default
