How to disable WordPress headers from loading s.w.org

Abstract

WordPress adds dns-prefetch in the header, which should be to pre-fetch emoticons and avatars from s.w.org. The purpose It is to improve the loading speed of web pages, but s.w.org is not accessible at all in China. Any pre-fetching or speed improvement are all in vain. Not only is it useless, but it may affect the speed, so ban it.

Add the following code to the theme functions.php template:

Method one

Method two

function remove_dns_prefetch( $hints, $relation_type ) {
if ( &#39;dns-prefetch&#39; === $relation_type ) {
return array_diff( wp_dependencies_unique_hosts(), $hints );
}
return $hints;
}
