 ### `ORIGIN`, `PROTOCOL_HEADER`, `HOST_HEADER`, and `PORT_HEADER`
 
 HTTP doesn't give SvelteKit a reliable way to know the URL that is currently being requested. The simplest way to tell SvelteKit where the app is being served is to set the `ORIGIN` environment variable:

 The [`RequestEvent`](@sveltejs-kit#RequestEvent) object passed to hooks and endpoints includes an `event.getClientAddress()` function that returns the client's IP address. By default this is the connecting `remoteAddress`. If your server is behind one or more proxies (such as a load balancer), this value will contain the innermost proxy's IP address rather than the client's, so we need to specify an `ADDRESS_HEADER` to read the address from:
