## Documentation

##### ~ `cookies` Array
The Cookie Parser sets an array `ctx.request.cookies` with the cookies that where sent with the request.
###### Example
Let's say we get a cookie (`Foo=Bar;`) We can access it in the context of Koa like this: `ctx.request.cookies['Foo']` => `"bar"`

##### ~ `cookie` Element
The Parser also defines a getter and setter for cookies

###### Example
```javascript
// Set a cookie
ctx.request.cookie.set({
	key: 'my_id',
	value: '12345678',
	path: '/',
	maxAge: 100,
	httpOnly: true,
	secure: false
})
```
