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

# ----------------------------------------------------------------------

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

# 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.

# 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

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 );

function get_cat_count_downloads_by_cat($cat_id){

global $wpdb;
$total_downloads = $wpdb->get_col($wpdb->prepare
("SELECT meta_value FROM wp_postmeta as pm
INNER JOIN wp_term_relationships as tr ON (pm.post_id = tr.object_id) 
INNER JOIN wp_term_taxonomy as tt ON (tr.term_taxonomy_id = tt.term_taxonomy_id) 
WHERE 1
AND tt.term_taxonomy_id = '".$cat_id."'
AND pm.meta_key = 'mp3_downloads'"));
	return array_sum( $total_downloads );
}

Когато регистрирате нов тип пост „custom post type“ във вашия function.php има опции rewrite, query_var, publicly_queryable, public. Те трябва да изглеждат така:

'rewrite'            => false,
'query_var'          => false,
'publicly_queryable' => false,
'public'             => false

От WordPress документацията:

rewrite Triggers the handling of rewrites for this post type. To prevent rewrites, set to false.

query_var 'false' - Disables query_var key use. A post type cannot be loaded at /?{query_var}={single_post_slug}

publicly_queryable Whether queries can be performed on the front end as part of parse_request().

public 'false' - Post type is not intended to be used publicly and should generally be unavailable in wp-admin and on the front end unless explicitly planned for elsewhere.

Сега отивате в „Permalinks Settings“ или ако сайта Ви е на български „Постоянни връзки“ и без да променяте нищо натиснете запазване на промените, което ще презапише настройките.
С това действие ще забрани достъпа до вашия „custom post type“ от предната част на сайта.
