[ale] Implementing XML-RPC

[cfowler at outpostsentinel.com (Christopher Fowler)]

I'm starting a project to implement XML-RPC on our embedded device. 
I've looked at the XML-RPC HOWTO and it seem to have left out some
details.  I need to know how the actual XML-RPC communications is done
between the client and the server over HTTP.

Questions:

1.  Does the client post a form where data in that form is the actual
XML-RPC code?  

2.  What does the server send back?  Pure XML or HTML.  

I've looked at the various API's and they do not seem to address
authentication.  Our device requires a user to loing via a form at
http://ip/login.  After the client receives a cookie they can then easiy
get to http://ip/xml-rpc and the start sending and receiving data.  


Thanks,
Chris
