Rack is a Ruby web server interface specification that provides a minimal abstraction layer between web servers and web applications to handle HTTP requests and responses. It aims to standardize how web applications interface with servers so that server interfacing code only needs to be written once. The Rack specification defines a simple API for web applications to handle requests and responses that various web servers and frameworks can implement, reducing duplicated work.
