a referrerPolicy

The no-referrer-when-downgrade SVG value specifies a request’s full referrerURL stripped for use as a referrer for requests: whose referrerURL and current URL are both potentially trustworthy URLs, or whose referrerURL is a non-potentially trustworthy URL.

Requests whose referrerURL is a potentially trustworthy URL and whose current URL is a non-potentially trustworthy URL on the other hand, will contain no referrer information. A Referer HTTP header will not be sent.
