Как да оптимизираме скоростта на WordPress чрез конфигуриране на кеша на браузера в .htaccess файла

Първо спираме ETag header-а тъй като ще използваме EXPIRES CACHING:

# ----------------------------------------------------------------------
# Expire Header
# ----------------------------------------------------------------------

# Use UTF-8 encoding for anything served text/plain or text/html
AddDefaultCharset UTF-8
# Force UTF-8 for a number of file formats

AddCharset UTF-8 .atom .css .js .json .rss .vtt .xml


# FileETag None is not enough for every server.

Header unset ETag


# Since we’re sending far-future expires, we don’t need ETags for static content.
# developer.yahoo.com/performance/rules.html#etags
FileETag None

# Send CORS headers if browsers request them; enabled by default for images.


# mod_headers, y u no match by Content-Type?!

SetEnvIf Origin ":" IS_CORS
Header set Access-Control-Allow-Origin "*" env=IS_CORS




# Allow access to web fonts from all domains.


Header set Access-Control-Allow-Origin "*"






Header set X-Powered-By "WP Rocket/2.8.14"
Header unset Pragma
Header append Cache-Control "public"
Header unset Last-Modified





Header unset Pragma
Header append Cache-Control "public"

Remove Query Strings

Добавете следния код в function.php (WordPress)

function _remove_script_version( $src ){
$parts = explode( '?ver', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
