Implements a CGI-based XML-RPC server.

require "xmlrpc/server"

s = XMLRPC::CGIServer.new

s.add_handler("michael.add") do |a,b|
  a + b
end

s.add_handler("michael.div") do |a,b|
  if b == 0
    raise XMLRPC::FaultException.new(1, "division by zero")
  else
    a / b
  end
end

s.set_default_handler do |name, *args|
  raise XMLRPC::FaultException.new(-99, "Method #{name} missing" +
                                   " or wrong number of parameters!")
end

s.serve

Note: Make sure that you don't write to standard-output in a handler, or in any other part of your program, this would cause a CGI-based server to fail!

Class Public methods
new(*a)

Creates a new XMLRPC::CGIServer instance.

All parameters given are by-passed to XMLRPC::BasicServer.new.

You can only create one XMLRPC::CGIServer instance, because more than one makes no sense.

Instance Public methods
serve()

Call this after you have added all you handlers to the server.

This method processes a XML-RPC method call and sends the answer back to the client.
