 11  ## Install
 12  
 13  This is a [Node.js](https://nodejs.org/en/) module available through the
 14  [npm registry](https://www.npmjs.com/). Installation is done using the
 15  [`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
 16  
 17  ```sh
 18  $ npm install parseurl
 19  ```
 20  
 21  ## API
 22  
 23  ```js
 24  var parseurl = require('parseurl')
 25  ```
 26  
 27  ### parseurl(req)
 28  
 29  Parse the URL of the given request object (looks at the `req.url` property)
 30  and return the result. The result is the same as `url.parse` in Node.js core.
 31  Calling this function multiple times on the same `req` where `req.url` does
 32  not change will return a cached parsed object, rather than parsing again.
 33  
 34  ### parseurl.original(req)
 35  
 36  Parse the original URL of the given request object and return the result.
 37  This works by trying to parse `req.originalUrl` if it is a string, otherwise
 38  parses `req.url`. The result is the same as `url.parse` in Node.js core.
 39  Calling this function multiple times on the same `req` where `req.originalUrl`
 40  does not change will return a cached parsed object, rather than parsing again.
