title: Is memcache data saved even after server restart?
body: <p>If a session handler is based off of memcached, and the memcache server is restarted, is the data saved or does all session information need to be recreated?</p>
  
  <p>If not, is memcached even a reliable for session storage? Or is it possible to create a session handler that uses both MySQL and memcache?  How?</p>
