XML-RPC - how to capture message?

Hi:

I have XML-RPC call passing from one module to another - at the moment there are in the same box.

Is there a way to capture XML-RPC calls in transit?

When XML-RPC calls are made across boxes are the signals encrypted?

Thanks,

Hari

What is the transport mechanism? HTTP?

Sounds to me like you are using an XML-RPC library.

When I hand coded an XML-RPC layer for an application (about 3-4 years ago) I included a hook to save all outgoing messages and their responses. This was used for later unit testing.

Perhaps your library has such a hook.

Do you want to always capture messages, or just when you're debugging?

For debugging, the easiest thing to do is go here:

http://www.pocketsoap.org

and download tcptrace. This is a socket proxy application that logs all the traffic that goes through it. I've used it to track down some serious problems.

As for your encryption question: if the URL you're using is http://, then it's not encrypted. If the url is https://, then it is.

Whoops, my bad, it should have been http://www.pocketsoap.com , not .org.
