Setting the cache in bootstrap

  protected function _initCaching() {
        $frontend = array(
            'lifetime' => 7200,
            'automatic_serialization' => true
        );
        $backend = array(
            'cache_dir' => sys_get_temp_dir(), /**automatically detects**/
        );
        $cache = Zend_Cache::factory('core', 'File', $frontend, $backend);
        Zend_Registry::set('cache', $cache);
    }
