No is not that. You are saying the basic cache system that include the basic pages.

When you go to include/smarty/libs/Smarty.class.php is this code.
Code:
  /**
     * This enables template caching.
     * <ul>
     *[*]0 = no caching
     *[*]1 = use class cache_lifetime value
     *[*]2 = use cache_lifetime in cache file
     *[/list]
     * @var integer
     */
    var $caching         =  0;

    /**
     * The name of the directory for cache files.
     *
     * @var string
     */
    var $cache_dir       =  'cache';
This is the cache system that include all pages.
