When using multiple memcached servers, the client software decides where to place a given key/value.
What if I save key1=val1 using PHP functions addServer() and set(), and later want to fetch that value from perl? How do I know which memcached server to connect to? What if I save 1000000 values to 3 memcached servers, and then decide to add a 4th server? The keyhash>server will not match compared to the 3 server setup.
