# 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
```
