'servers' => array('localhost:11211'),

$TYPO3_CONF_VARS['SYS']['caching']['cacheConfigurations']['cache_pagesection']['backend'] = 't3lib_cache_backend_MemcachedBackend';
$TYPO3_CONF_VARS['SYS']['caching']['cacheConfigurations']['cache_pagesection']['options'] = array(

);

$TYPO3_CONF_VARS['SYS']['caching']['cacheConfigurations']['cache_hash']['backend'] = 't3lib_cache_backend_MemcachedBackend';
