HTTP response freshness testing

fresh(req, res)

Check freshness of req and res headers.

When the cache is "fresh" __true__ is returned, otherwise __false__ is returned to indicate that the cache is now stale.

Example:

var req = { 'if-none-match': 'tobi' };
var res = { 'etag': 'luna' };
fresh(req, res);
// => false

var req = { 'if-none-match': 'tobi' };
var res = { 'etag': 'tobi' };
fresh(req, res);
// => true

Installation

$ npm install fresh
