failover

The setup is one server (Windows 2008) at one location with two incoming connections. As the server has to interface with various on-site devices, and will have a small number of incoming connections, a data center is not an option, and instead cable/dsl connections must be used.

The goal is that users visit https://service.site.com and are sent to either the primary IP address or a secondary IP if the primary is down.

I've seen advice to use round robin DNS for this, but caching an IP for a downed interface is something I'd like to avoid.

Is something like this possible with these constraints?

I am wondering conceptually how load-balancing works on the EJB-level (not web session replication) with Java EE containers like Glassfish.
