Note Jason's last sentence: don't recommend leaving this enabled too long. It is VERY verbose and fills up the log file. What is your need for looking at the request/response payloads? If you are using Perl, there is a nice built-in client-side tracing facility built into SOAP::Lite. That's a nice alternative. I've found that the only real time I've needed to look at the payloads is when I'm using a loosely typed language like Perl or Python and need to make sure I'm packing the parameters correctly. Is that your case?
