new(*addresses)
public
Creates a new
MemCacheStore object, with the given memcached server addresses.
Each address is either a host name, or a host-with-port string in the form
of “host_name:port”. For example:
ActiveSupport::Cache::MemCacheStore.new("localhost", "server-downstairs.localnetwork:8229")
If no addresses are provided, but ENV['MEMCACHE_SERVERS'] is
defined, it will be used instead. Otherwise, MemCacheStore will
connect to localhost:11211 (the default memcached port). Passing a
+Dalli::Client+ instance is deprecated and will be removed. Please pass an
address instead.

ActiveSupport.deprecator.warn(<<~MSG)
Initializing MemCacheStore with a Dalli::Client is deprecated and will be removed in Rails 7.2.
Use memcached server addresses instead.
