Re: Load balancing SSL sessions

I believe there is an issue with failover, however, with this route (thus, the second use case for load balancers - failover). If an IP address in the DNS list goes down, it can take up to 48 hours before the DNS maps are updated to reflect the loss of one of the IPs. In the meantime, clients
