-HTTP response freshness testing
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```
-$ npm install fresh
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var fresh = require('fresh')
-```
-
-### fresh(reqHeaders, resHeaders)
-
-Check freshness of the response using request and response headers.
-
-When the response is still "fresh" in the client's cache `true` is
-returned, otherwise `false` is returned to indicate that the client
-cache is now stale and the full response should be sent.
-
-When a client sends the `Cache-Control: no-cache` request header to
-indicate an end-to-end reload request, this module will return `false`
-to make handling these requests transparent.
-
-## Known Issues
-
-This module is designed to only follow the HTTP specifications, not
-to work-around all kinda of client bugs (especially since this module
-typically does not recieve enough information to understand what the
-client actually is).
-
-There is a known issue that in certain versions of Safari, Safari
-will incorrectly make a request that allows this module to validate
-freshness of the resource even when Safari does not have a
-representation of the resource in the cache. The module
-[jumanji](https://www.npmjs.com/package/jumanji) can be used in
-an Express application to work-around this issue and also provides
-links to further reading on this Safari bug.
-
-## Example
-
-### API usage
-
-<!-- eslint-disable no-redeclare, no-undef -->
-
-```js
-var reqHeaders = { 'if-none-match': '"foo"' }
-var resHeaders = { 'etag': '"bar"' }
-fresh(reqHeaders, resHeaders)
-// => false
-
-var reqHeaders = { 'if-none-match': '"foo"' }
-var resHeaders = { 'etag': '"foo"' }
-fresh(reqHeaders, resHeaders)
-// => true
-```
-
-### Using with Node.js http server
-
-```js
-var fresh = require('fresh')
-var http = require('http')
-
-var server = http.createServer(function (req, res) {
-  // perform server logic
-  // ... including adding ETag / Last-Modified response headers
-
-  if (isFresh(req, res)) {
-    // client has a fresh copy of resource
-    res.statusCode = 304
-    res.end()
-    return
-  }
-
-  // send the resource
-  res.statusCode = 200
-  res.end('hello, world!')
-})
-
-function isFresh (req, res) {
-  return fresh(req.headers, {
-    'etag': res.getHeader('ETag'),
-    'last-modified': res.getHeader('Last-Modified')
-  })
-}
-
-server.listen(3000)
-```
