 Calling `cookies.set(name, ...)` causes a `Set-Cookie` header to be written, but it _also_ updates the internal map of cookies, meaning any subsequent calls to `cookies.get(name)` during the same request will return the updated value. Under the hood, the `cookies` API uses the popular `cookie` package — the options passed to `cookies.get` and `cookies.set` correspond to the `parse` and `serialize` options from the `cookie` [documentation](https://github.com/jshttp/cookie#api).
