HTTP(S) protocol is not supported

[jsardev]

The README states that the client supports http protocol, but it doesn't.

We're trying to use the http(s) protocol because the default ws(s) breaks after some while when the app is working. We keep getting a HRANA_WEBSOCKET_ERROR: WebSocket was closed error – that's a different topic, but I wanted to give some rationale on why we're trying to do this.
