I've got two servers, equal capabilities in terms of processing power and load. What I am trying to accomplish is this: (I already own and run DNS servers so this shoudln't be a problem).
Server A will serve ALL incoming requests to sub.domain.com Server B will ONLY serve while server A is down, and if it needs to wait a few moments to decide, thats OKAY.
Is it possible? The weighted round robin doesn't work for what I need, nor does regular round robin, since it will only advance to the next server if the first request is successfully delivered.
Is there a way to make it so that if sub.domain.com on server A is unavailable, forward to server B until A comes online?
Thanks, this will really help with the consistency of my project.
