Hash Load Balancing

The solution with checking which nodes are currently active myself seems a little slow - and I can't imagine it scales very well...

 

 

I originally tried "persist uie", but the problem I had is that initially, should one server go down, all load would be split across the remaining servers BUT when I bring the broken server back up, it no longer gets any traffic as all '100' different values are mapped to the other servers until a timeout happens.

 

 

This is even worse during a complete restart, because with stupid luck, 1 of the 4 servers may get ALL the traffic.

 

 

Does persist hash not also have the same problem?
