Revolution has the MD5digest function.  There is a library that can help 
in http POST and I believe there is a way to insert headers--I have not 
used it.

For your app, you might want to simply use TCP directly.

XML libraries are about, but you may be fine by pasting together some 
strings.

Creating the digest involves some string creation and using the digest 
function a few times.

Get a good http reference.  You will need to look at a couple chapters.  
I have _HTTP Essentials_ by Stephen Thomas, but I am no judge of how 
good this is.  This will be handy even should you find Rev will do most 
of the work.  You will need an XML reference, too.  Most of those 
include much more than you need; you probably need only basic XML 
syntax, a single chapter.

The digest authentication comes in (at least) the original and 
extra-crispy, I mean, improved versions.  Check on which is used.

I hope this gets you started.
