manage the Vary header of a HTTP response - Node.js module

This package provides a simple module to manage the fields of the Vary header in a HTTP response.

The Vary HTTP response header determines how to match future request headers to decide whether a cached response can be used rather than requesting a fresh one from the origin server. It is used by the server to indicate which headers it used when selecting a representation of a resource in a content negotiation algorithm.

Node.js is an event-based server-side JavaScript engine.
