Comment (by kb):
Is your goal a distinct "primary/failover" setup (use server B only if A
failed, and revert back to A when it becomes healthy again) or generalized
persistence?
I think you could implement both in VCL, so the question that comes to my
mind is whether its use would be widespread enough to justify added
director complexity.
I think primary/failover might be worthy, but adding features to the
"director" could be a slippery slope -- there are literally hundreds of
major features that could be added that exist in, say, LVS or Netscalers
or BigIPs.
The other feature I'd like to see is a least-connections director. Past
that, I'm not sure I wouldn't implement more complex
balancing/persistence/etc on dedicated up-stream systems.
Just my US$0.02,
Ken
