A pure ruby library for accessing memcached.
Just install the gem:
$ sudo gem install memcache-client
With one server:
CACHE = MemCache.new 'localhost:11211', :namespace => 'my_namespace'
Or with multiple servers:
CACHE = MemCache.new %w[one.example.com:11211 two.example.com:11211], :namespace => 'my_namespace'
See MemCache.new for details. Please note memcache-client is not thread-safe by default. You should create a separate instance for each thread in your process.
Using memcache-client with Rails
There's no need to use memcache-client in a Rails application. Rails 2.1+ includes a basic caching library which can be used with memcached. See ActiveSupport::Cache::Store for more details.
memcache-client is maintained by Mike Perham and was originally written by Bob Cottrell, Eric Hodel and the seattle.rb crew.
