Parse a URL with memoization.
## Install
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):
```sh
$ npm install parseurl
```
## API
```js
var parseurl = require('parseurl')
```
### parseurl(req)
Parse the URL of the given request object (looks at the `req.url` property)
and return the result. The result is the same as `url.parse` in Node.js core.
Calling this function multiple times on the same `req` where `req.url` does
not change will return a cached parsed object, rather than parsing again.
### parseurl.original(req)
Parse the original URL of the given request object and return the result.
This works by trying to parse `req.originalUrl` if it is a string, otherwise
parses `req.url`. The result is the same as `url.parse` in Node.js core.
Calling this function multiple times on the same `req` where `req.originalUrl`
does not change will return a cached parsed object, rather than parsing again.
