Rack::Cache is suitable as a quick, drop-in component to enable HTTP caching for Rack-enabled applications that produce freshness (Expires, +Cache-Control+) and/or validation (+Last-Modified+, ETag) information.
Create with default options:
require 'rack/cache' Rack::Cache.new(app, :verbose => true, :entitystore => 'file:cache')
Within a rackup file (or with Rack::Builder):
require 'rack/cache' use Rack::Cache do set :verbose, true set :metastore, 'memcached://localhost:11211/meta' set :entitystore, 'file:/var/cache/rack' end run app

Create a new Rack::Cache middleware component that fetches resources from the specified backend application. The options Hash can be used to specify default configuration values (see attributes defined in Rack::Cache::Options for possible key/values). When a block is given, it is executed within the context of the newly create Rack::Cache::Context object.
