Request.referrerPolicy

The referrerPolicy read-only property of the Request interface contains the referrer policy governing the referrer for the request.

Syntax

var myReferrerPolicy = request.referrerPolicy;

Value

A DOMString representing the request's referrerPolicy, as defined in ReffererPolicy. Possible values are:

• An empty string if there is no referrer policy set.
• no-referrer
• no-referrer-when-downgrade
• origin-only
• origin-when-cross-origin
• unsafe-url

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
