Actually that header is what the client thinks the server is called.  It is
used when you use virtual servers.  Think of an ISP that hosts many sites off
the same machine.  The web server examines the Host header to see which
server's content to serve up.  (In the olden days you would have to make
one server IP address per web site!)

Technically the Host header is part of HTTP/1.1 but most web browsers specify
it (even when speaking HTTP/1.0).  I don't know if XML-RPC clients are
required to specify the Host header, but you will probably find in practise
that most do.
