Hi Mike,

 

 

If their client(s) don't do a DNS lookup while using an active TCP connection, I think you'd need to reset their connections to force a lookup and move to the other datacenter. I guess you could proxy traffic to the new datacenter with an iSession tunnel, but I think that defeats your point of moving traffic to the second datacenter.

 

 

What protocol(s) are you servicing? Is there a concept of redirecting the client to a new FQDN which is specific to the other datacenter? Or a way to force the client to do a new DNS resolution which doesn't involve resetting the connection?
