Just tried that out. Quite a nice dump, but I don't see the body in the output.
I'm tracing ActiveSync via a proxy, wanting to glean the WBXML in the body, kinda like using a proxy as a sniffer.

If I have to develop this, is the debug feature the right place?

I could see creating a filter module, maybe? Note that I also want to be able to capture & display POST data going toward the server.

Advice appreciate.
