Websocket protocol with wifi shield

Hello everyone.... I bought the following shield: http://arduino.cc/en/Main/ArduinoWiFiShield and I'm using arduino Uno board...

I'm developing a website that using Websocket protoocol to connect to my arduino, can I establish connection from my website to arduino using websocket protocol over this shield?

What kind of library do I need to use to develop a websocket app for the arduino?

Thanks in advance... :)
