How can you configure a machine to pretend it has more than
one network interface? Do you know if there's a standard
way to do this in UNIX?
% address to abcd.com, assign another to xyz.com, and run a server which
% behaves differently depending on which IP address is used to contact
% it. The important thing is that the IP addresses must be distinct,
% since an HTTP client doesn't try to tell the server what it thinks the
% server's name is.
%
% The server you use has to be aware of this arrangement as well, of
% course. Patches are available for the NCSA server (and probably for
% CERN as well); Apache, an NCSA derivative, comes with this code
% integrated in to the main body (and we've even gotten around to
% documenting it). See
%
% http://www.hyperreal.com/apache/docs/virtual-host.html
%
% for details on how this works...
