CacheCow is a library for implementing HTTP caching on both client and server in ASP.NET Web API. It uses message handlers on both client and server to intercept request and response and apply caching logic and rules.

This library is setup to work with minimal setup and is flexible to allow for custom or complex resource organisation.
