Rack

Rack is a minimal, modular interface and invocation convention that operates between Ruby web servers and web applications to standardize how HTTP requests and responses are exchanged.

It translates raw HTTP requests into a CGI-style environment defined by RFC 3875, supports middleware stacking for step-by-step request and response processing, and is implemented by servers such as Phusion Passenger, Puma, Unicorn, and Thin.
