/**
 * Execute a module page - this is an alternative to invoking /myItop/env-production/myModule/somePage.php
 *
 * The recommended way to build an URL to a module page is to invoke utils::GetAbsoluteUrlModulePage()
 * or its javascript equivalent GetAbsoluteUrlModulePage()
 * 
 * To be compatible with this mechanism, the called page must include approot
 * with an absolute path OR not include it at all (losing the direct access to the page)
 * if (!defined('__DIR__')) define('__DIR__', dirname(__FILE__));
 * require_once(__DIR__.'/../../approot.inc.php');
