Subject: [PATCH] Enhance WebSocket testing script to include session ID
 handling

This commit updates the `testWebSocket.js` script to extract and utilize the session ID from the HTTP polling response. The WebSocket upgrade request is modified to include the session ID when available, improving the accuracy of the upgrade tests. Additionally, detailed logging for response bodies is added to aid in diagnosing potential issues during the WebSocket upgrade process.
