`$.headers` holds the request headers with lowercase names. `$.cookie(name)` reads a cookie of the request and `$.cookie(name, value, expiration)` writes one to the response. Response headers are set on `$.response.headers`.

```js controllers/headers.js
exports.install = function() {
	ROUTE('GET /headers/', headers);
	ROUTE('GET /visit/', visit);
};

function headers($) {
	$.response.headers['x-powered-by-forge'] = 'yes';
	$.json({ agent: $.headers['x-agent'] || null });
}

function visit($) {
	var count = ($.cookie('visits') || '0').parseInt() + 1;
	$.cookie('visits', count + '', '1 day');
	$.json({ visits: count });
}
```
