Displays a referrer strict-origin-when-cross-origin meta tag.

Description

Outputs a referrer strict-origin-when-cross-origin meta tag that tells the browser not to send the full URL as a referrer to other sites when cross-origin assets are loaded.

Typical usage is as a ‘wp_head’ callback:

add_action( 'wp_head', 'wp_strict_cross_origin_referrer' );

Source

function wp_strict_cross_origin_referrer() {
	?>
	<meta name='referrer' content='strict-origin-when-cross-origin' />
	<?php
}
