Complex Default Routes

Say a server has three ethernet adapters installed:

192.168.1.x on class C
192.168.2.x on class C
172.16.1.x on class C and this is the default route

If a packet from the Internet comes into 192.168.1.x, as I understand it the
return packet will go out on 172.16.1.x since that is the default outgoing
route. Is there a way to configure things so that TCP connections will
"stick" to the same adapter on which the incoming connection request
initiated? If a connection comes in on 192.168.1.x I want the entire
TCP connection to live on that adapter.
