The server keeps a play queue per client, identified by the X-Queue-Id header. The client sends the ID it has for the selected server with every request and keeps the one in each response, which is new after a reset or a sync. The IDs are saved per server in the [queues] section of settings.cfg, so the game goes on with the same queue after a restart. HttpTransport now passes the response headers on to the client.
