Running xmlrpc client on specific port

[Lars Schnoor]

Hi everyone
I have seen that a xmlrpc server can be created giving both a network 
port and an IP-address. For me this sounds like the server can be made 
to listen on a specific network interface. When creating a xmlrpc client 
only a port and address of the xmlrpc server is given. Is it possible to 
specify a IP-address for the client to use for connecting to the server? 
I mean if the client computer has multiple network cards and one 
specific should be used to connect to the server running the xmlrpc 
server software.
Thanks in advance!
Lars
