In the case of native WebSocket connection, only the initial request/response is a HTTP message. All the subsequent traffic will switch to the WebSocket protocol, which makes it diffcult to trace the wire message. Chrome supports WebSocket natively, hence WebSocket native protocol is adapted when using Chrome to access the web enabled by TWM.

With the developer tools in the newest Chrome release, you can see the WebSocket traffic coming from and going to your browser,

1). Open Chrome developer tool (Menu -> Tools -> Developer Tools), then click 'Network' tab.

2). Choose the "WebSockets" filter at the bottom to show only WebSocket connections.
  
3). Click on the WebSocket connection on the left panel.
  
4). You should notice that there are 'Headers', 'Preview', 'Response', etc. sub-tabs to the right panel.
  
5). Once data starts flowing through WebSocket connection, a 'WebSocket Frames' subtab will appear. All data going in either direction will be logged.
