RackRequestCache

Provides a caching layer that exists only within a single Rack request. The middleware itself is thread-safe; each thread has its own cache.

Installation

Install as usual: gem install rack-request_cache or add gem 'rack-request_cache' to your Gemfile. Note that Ruby 2.0 is required.

Usage

Add the middleware to your app (likely in your config.ru):

require 'rack/request_cache'

use Rack::RequestCache
run MyApp

Then, whenever you wish to cache something:

Rack::RequestCache.cache do
  expensive_operation
end
