self.new(*addresses) — ActiveSupport::Cache::MemCacheStore

self.new(*addresses)

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.

Parameters

addresses rest
