Ring

Ring is a Clojure web applications library inspired by Python's WSGI and Ruby's Rack. By abstracting the details of HTTP into a simple, unified API, Ring allows web applications to be constructed of modular components that can be shared among a variety of applications, web servers, and web frameworks.

The SPEC.md file at the root of this distribution provides a complete description of the Ring interface. The Wiki contains more in-depth documentation on how to use Ring.
