In some cases, this referer metadata parameter can be used when a website wants to control the referer information that a page sends to the server for a number of reasons.

parameter

The metedata property of the referer can set the content property value to the following collection:

never
always
origin

outcome

If the value of referer-policy is never: remove the referrer in http head;
If the value of referer-policy is default: If the current page uses the https protocol and the resource to be loaded uses the normal http protocol, set the HTTP header to empty.
If the value of referer-policy origin: only sends the origin part;
If the value of referer-policy is always: do not change the value of the referer in the http header;

For example

If the page contains the following meta tags, all requests from the current page will not carry the > referer:<meta name="referrer" content="never"

If the page contains the following meta tag, HTTP requests from the current page will only carry the origin part: <meta name="referrer" content="origin">
