## useRequestHeaders

Within your pages, components, and plugins you can use `useRequestHeaders` to access the incoming request headers.

```js
// Get all request headers
const headers = useRequestHeaders()

// Get only cookie request header
const headers = useRequestHeaders(['cookie'])
```

::alert{icon=👉}
On client side, `useRequestHeaders` will return an empty object.
