Am I right in assuming that you're establishing application-layer sessions to two hosts with two different IP addresses (outside of your control) which provide (close to) identical services? If so, there's not much you can do outside of the application itself (at least if you want a semi-robust solution).
You could try (reverse) load balancer, but even then the application session would have to be disconnected before being switched over to the other host.
