Remove Req from the Websocket interface After the switch to Websocket, we are no longer in a request/response scenario, therefore a lot of the cowboy_req functions do not apply anymore. Any data required from the request will need to be taken from Req in init/2 and saved in the handler's state. 2016-08-12 19:27:23 +02:00			`-export([websocket_handle/2]).`
