[TYPO3-v4] What is happening with id 0?

[Steffen Kamper]

Hi,

i figured it out

$TYPO3_CONF_VARS['SYS']['caching']['cacheConfigurations']['cache_pages'] 
= array(
   'frontend' => 't3lib_cache_frontend_StringFrontend',
   'backend' => 't3lib_cache_backend_DbBackend',
   'options' => array(
     'cacheTable' => 'cachingframework_cache_pages',
     'tagsTable' => 'cachingframework_cache_pages_tags',
     'compression' => TRUE,
   ),
);

the 'frontend' => 't3lib_cache_frontend_StringFrontend' doesn't work, is 
defect or unusable
