# node-fresh 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: ```js 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 ```
