Hi Jeffrey,

I kept the folowing configuration only:
config.cache_store = :mem_cache_store
and it works.

But now i want to try other way that is creating an instance like this:

memcache_options = {
   :compression => true,
   :debug => false,
   :namespace => "mem-#{RAILS_ENV}",
   :readonly => false,
   :urlencode => false
}

memcache_servers = [ ''127.0.0.1:11211'' ]

CACHE = MemCache.new(memcache_options)
CACHE.servers = memcache_servers

and i commented out the following:
config.cache_store = :mem_cache_store

But during server startup it throws the following error:

trying above?
