Jetty 8.1.1 Client acknowledgment of Websocket client

Question

I am using Jetty 8.1.1 app for web api applications.
I need to update the headers with ("Sec-WebSocket-Protocol", "xsCrossfire")and("Authorization", "Basic TLVWQMZqRr2hasYnZoI=")

WebSocketClientFactory factory = new WebSocketClientFactory();
factory.start();
client = factory.newWebSocketClient();
client.getCookies().put("Sec-WebSocket-Protocol", "xsCrossfire");
client.getCookies().put("Authorization", "Basic TLVWQMZqRr2hasYnZoI=");
Future<Connection> conn = client.open(uri, (WebSocket) this);
System.out.printf("Connecting to : %s%n", uri);

The request looks like:

Host: iltlvl262:8000\r\n
Upgrade: websocket\r\n
Connection: Upgrade\r\n
Sec-WebSocket-Version: 13\r\n
Sec-WebSocket-Key: FHKTsICO2vqGCxXVwLkH4Q==\r\n
Cookie: Sec-WebSocket-Protocol=xsCrossfire\r\n
Cookie: Authorization="Basic TLVWQMZqRr2hasYnZoI="\r\n

expected request:

Host: iltlvl262:8000\r\n
Upgrade: websocket\r\n
Connection: Upgrade\r\n
Sec-WebSocket-Version: 13\r\n
Sec-WebSocket-Key: FHKTsICO2vqGCxXVwLkH4Q==\r\n
Sec-WebSocket-Protocol: xsCrossfire\r\n
Authorization: "Basic TLVWQMZqRr2hasYnZoI="\r\n

How to correctly perform a handshake in version 8.1.1?

Some good news and some bad news.

Firstly, the good news:

Sec-WebSocket-ProtocolUse the following to set the title .

client.setProtocol("xsCrossfire");

before using client.open()

Next, the bad news:
