 Note that some properties of `RequestEvent` are different inside remote functions. There are no `params` or `route.id`, and you cannot set headers (other than writing cookies, and then only inside `form` and `command` functions), and `url.pathname` is always `/` (since the path that’s actually being requested by the client is purely an implementation detail).
