Monitoring network communication between Flash application and CF server

I need help finding an effective method to monitor and capture the data exchange between my Flash-based frontend and a ColdFusion backend system. The communication happens through AMF protocol which makes standard debugging more challenging.

I normally rely on network monitoring tools for regular HTTP traffic analysis, especially when dealing with standard text-based or XML requests and responses. However, these tools don’t provide much insight when working with binary data formats like AMF transmitted over HTTP connections.

While I do have full access to both the client-side and server-side source code, I’m specifically looking for a non-intrusive approach that allows me to observe the network traffic in any Flash and ColdFusion setup without requiring modifications to the backend infrastructure.
