Adding custom columns in the Web Sockets history - Port Swigger

Summary: PortSwigger documented a Burp Suite feature that lets users add custom columns to the WebSockets history table using Java-based scripts, loaded from a Bambda library or written from built-in templates. The scripts use two Montoya API objects, ProxyWebSocketMessage and Utilities, and PortSwigger warns that slow or resource-intensive scripts can slow down Burp.
Why it matters: The same scripting that gives analysts a focused view of WebSocket traffic can degrade the tool itself, so a poorly written column script carries a direct performance cost for the team relying on Burp during an investigation.
