Thanks Ryan,
Here's the thing I need that might be hard, I need to be able to satisfy these assertions:
For source networks A, B, and C, dest-node A is preferred, B is a usable standby, but dest-node C should never be tried (even if it's up).
For source networks C, D, and E, dest-node C is preferred, B is a usable standby, but dest-node A should never be tried (even if it's up).
Do you think HAProxy is up to that?
