Fonctions de rappel sur clé absente
If you want to use 'memcacheD' extention not 'memcache' (there are two diffrent extentions) for session control, you should pay attention to modify php.ini
Most web resource from google is based on memcache because It's earlier version than memcacheD. They will say as following
session.save_handler = memcache
session.save_path = "tcp://localhost:11211"
But it's not valid when it comes to memcacheD
you should modify php.ini like that
session.save_handler = memcached
session.save_path = "localhost:11211"
Look, there is no protocol indentifier
Support des sessions
Memcached fournit un gestionnaire de sessions qui peut être utilisé pour stocker les sessions sur memcache. Une instance distincte de memcached est utilisé en interne, ce qui fait que vous pouvez avoir un pool de serveur différent, si nécessaire. Les clés de sessions sont stockés avec le préfixe memc.sess.key., alors soyez-en conscient si vous utilisez le même serveur pour les sessions et pour le cache.
-
session.save_handlerstring -
Donnez-lui la valeur de memcached pour activer le support des sessions sur memcached.
-
session.save_pathstring -
Définit une liste de valeurs séparés par des virgules, avec la syntaxe nomdhote:port, à utiliser pour le pool de serveurs de sessions. Par exemple, "sess1:11211, sess2:11211".

If you are using the memcache class for session handling your key is the PHP session ID. This is different than when using the memcached class.
Example with memcache:
GET nphu2u8eo5niltfgdbc33ajb62
Example with memcached:
GET memc.sess.key.nphu2u8eo5niltfgdbc33ajb62
For memcached, the prefix is set in the config:
memcached.sess_prefix = "memc.sess.key."

While the previous poster has a point that Memcached can and will cleanup to make room for it's keys, the likelihood of active sessions (due to the likelihood that they will be written to again within 30 seconds) is fairly low provided you have your memory allocation properly alloted.
