May 02, 2016Now suppose the are a few hundred clients behind the same public NAT. They call end up on the same web server, node A, due to the persistence rule. What happens when the 101st user from that same public NAT makes a connection?

- Status of
setting (Persistence Profile)Override Connection Limit
Assuming this is enabled, 101th connection will go to node A
When disabled, the persistence record will be discarded and connection will go to another node (load-balancing occurs) - If
setting is disabled and no other pool members are available, TCP-RST will be sent to client which results in a generic "Connection Has Been Reset" web-browser errorOverride Connection Limit
