Re: testing email based e-commerce system with .xdp extension - looking for input

So what you mean is that they use SSL to encrypt the connection,
pretty standard.
They didn't show up because SSL usually starts using port 445, and you
http proxy probably only listens to port 80. Even if it would actually
be aware of port 445 it wouldn't be useful, as it is encrypted. You
can intercept the encrypted connection with ettercap for example.

xpd = XML pipeline document

As you seem quite imprecise, is it really a webservice or does it only
look like one?

Check for compliance with PCI 1.1.

So you been hired to verify the security of the e-commerce site?
I am always amazed :)
