There are a couple of ways you can do this. You can add an entry in
/etc/hosts (or equivalent) with the new address and curl will use that
to connect to the host. Or, you can use the -H trick you were so close to
getting working. -H takes a whole HTTP header, so you need to do
-H 'Host: www.domain.com' to set the virtual host.
