How to maintain cache update on different memcached servers?

[Daniel Beckham]

Of course it would be duplicated if you had two separate memcached 
pools.  Are you being intentionally obtuse?

As Bash Coder has tried to explain, you normally only use a single pool 
of all of your memcached servers and the client uses a hash value to 
determine which server a particular piece of data is stored on.  End. 
Of. Story.
