How does xmlrpc work ?

[hide1713 at gmail.com]

Hi everyone
I am working on a system which used XMLRPC to communicate between
hundreds of computer. One administrative computer keeps hundreds of
xmlrpc instance of other computers.  I want to know if evey instance
use a single connection and keep it alive forever OR create a new
connection when a method is called and end it after the call is
finished?

Thank you
