$server_key
, array $keys
[, bool $with_cas

Memcached::getDelayed(), except that the free-form
server_key can be used to map the
keys to a specific server.
server_key
The key identifying the server to store the value on.
keys
Array of keys to request.
with_cas
Whether to request CAS token values also.
value_cb
The result callback or NULL.
Returns TRUE on success or FALSE on failure.
Use Memcached::getResultCode() if necessary.
