Most server applications that LISTEN to interfaces can be configured to
listen on one, the other, or both interfaces.

Apache is a good example. It works great with two NICs. It can be
configured to listen one interface, leaving the other one alone. Or it
can listen to both. Other good examples include dnsmasq, postfix, mysql....
However, applications that act as CLIENTS will send packet out, using
whatever the kernel's routing table tells them to use.
