Hi, can somebody please help me understand what the PHP code below is meant to do?
PHP Code:
<?php

define('VB_ENTRY', 'forum.php');
// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
// pre-cache templates used by all actions
$globaltemplates = array(
'ws_contact_forum',
);
// pre-cache templates used by specific actions
$actiontemplates = array();
// ######################### REQUIRE BACK-END ############################
