Rack::PerRequestCache

Simple module for caching arbitrary objects / constructs during a request.

require 'rack/per_request_cache'
use Rack::PerRequestCache

# Gemfile
gem 'rack-per_request_cache', require: 'rack/per_request_cache'

# config/application.rb
config.use 'Rack::PerRequestCache'

If Rack::PerRequestCache.clear_cache is not called, then no caching is performed. When hooked up as a middleware (see above), then the cache is enable dy default during the request lifecycle.
