To do this, ipvs would need to act as a proxy, accepting the connection and
wait for the host: header before redirecting traffic. Since the realserver
might be refusing the connection it's not enough to use normal 'direct
routing' afterwards. It looks to me like a squid module that supports
failover like loadbalancing would be a more suitable solution
