Subject: Re: Memcache reset on rails 2.3 with preload
Date: Thu, 10 Mar 2011 16:14:27 -0600	[thread overview]

Eric,

No, I'm using the "memcached" gem which has a binding for libmemcached
(and is much faster than the memcache-client gem).

The memcached gem has a compatibility wrapper (Memcached::Rails) which
is made to be backwards compatible with memcache-client.
