  • JSON-P
  • Rack::Cache is suitable as a quick drop-in component to enable HTTP caching.
  • Rack::ESI is a small (but still very useful!) subset of ESI (Edge Side Includes).
  • CloudKit includes OpenIDFilter, OAuthFilter, and RESTful JSON storage
  • Rack::Config – Shared configuration for cooperative middleware.
  • Rack::OpenID provides a more HTTPish API around the ruby-openid library.
  • Rack::Debug
  • Rack::AbstractFormat
  • Rack::RespondTo allows triggering different actions based on requested media type.
  • Rack::SupportedMediaTypes specify an app’s supported media types.
  • Rack::AcceptMediaTypes determine the request’s prefered media type.
  • Rack::MultipartRelated parses multipart/related requests and rebuild a simple/merged parameters hash.
  • Rack::Heartbeat Add a configurable heartbeat/health-check/ping url to your app
  • Rack::Honeypot acts as a spam trap.
  • Rack::GoogleAnalytics embeds Google Analytics tracking code.
  • Rack::Embed embeds small images via the data-url (base64) if the browser supports it. This reduces http traffic.

  • Rack::Batik::SVG transcodes SVG pictures to JPEG
  • Rack::Referrals extracts referring search engine info
  • Muster parses some or all of the query string in varying formats into hashes. Helps adding human friendly (not rack/rails nested) query string options to APIs and such.
