Request.referrer
The referrer read-only property of the
Request interface is set by the user agent to be the referrer of the
Request. (e.g., client, no-referrer, or a URL.)
Note: If referrer's value is no-referrer,
it returns an empty string.

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 in a variable:
var myRequest = new Request('flowers.jpg');
var myReferrer = myRequest.referrer; // returns "about:client" by defaultSpecifications
