What I do, is to create a stream where I want an eventual debug
message to show up, and then add it to all outgoing requests with the
following statements:
	    HTRequest_setDebugStream(request, debug);
	    HTRequest_setDebugFormat(request, WWW_SOURCE);
(where "debug" is the HTStream* where you want the error message to
end up)

Maybe you can adjust the default output format of the POST request?
Maybe calling
	HTRequest_setOutputFormat(request, WWW_RAW);
on requests before sending them will do the trick?
