-/**
- * TMemCacheSession class
- *
- * TMemCacheSession provides access for storing sessions in memcache.
- * Beware, session data will be stored in memory. Old data will be flushed
- * if you run out of cache memory. Configure your memcache carefully.
- * Keep in mind that memcached is a cache not a database. It is fast,
- * but not reliable storage.
