Forbid WordPress header from loading s.w.org

00:31:43, September 8, 2016 WordPress sixty 14.1K Reading mode

abstract WordPress should add dns prefetch to its header in order to pre acquire emoticons and avatars from s.w.org, in order to improve the speed of page loading, but s.w.org is not accessible in China at all, so what is pre acquired and what is faster

After upgrading to WordPress 4.6, a child shoe found that a:

<link rel='dns-prefetch' href='//s.w.org'>

WordPress should add dns prefetch to the header in order to s.w.org Pre acquire emoticons and avatars to improve the speed of web page loading, but s. W.org is not accessible in China, Any pre acquisition or speed increase is a bubble. It is not only useless, but may affect the speed. It is prohibited.

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

Method 1

remove_action( 'wp_head', 'wp_resource_hints', 2 );

Method 2

function remove_dns_prefetch( $hints , $relation_type ) {
if ( 'dns-prefetch' === $relation_type ) {
return array_diff ( wp_dependencies_unique_hosts(), $hints );
}
return $hints ;
}
add_filter( 'wp_resource_hints', 'remove_dns_prefetch', 10, 2 );

Method 2 seems to be more compatible.

Attached is a forbidden emoticon code

// Remove emoji script
remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
remove_action( 'wp_print_styles', 'print_emoji_styles' );
add_filter( 'emoji_svg_url', '__return_false' );

    @ I love sports bike network Brother Bird said he would not use CDN to suggest not to use acceleration! I accelerated, but the speed became slower!

      @ Pioneer Blog It is not because of the cdn acceleration you used, but because the header automatically adds/adds the dns prefetch after the WordPress program is upgraded to version 4.6.

At present, there is no upgrade, because 4.6 is in English but not in Chinese, so I will not upgrade for fear of making mistakes

  @ Yang Zeye's Blog I upgraded to 4.6 a few days ago, and I also upgraded to 4.6.1 yesterday. I didn't find any problems. If you have always used the simplified Chinese version, the direct background update will still be in Chinese. If the simplified Chinese version is updated later, the background can also update the translation.

Can we only remove s.w.org and allow other dns prefetch. After hosting js to Baidu, the website will add link rel='dns prefetch' href='//apps. bdimg. com'/in the header, and Baidu will be banned by both methods. Note: The server is abroad
