Just use destination address affinity instead, please. It results in a single persistence record applicable to all clients requesting the virtual. The record actually contains the virtual servers IP address (destination address affinity) and will be deleted/replaced in case the mapped pool member fails and a re-selection happens. Finally all traffic sticks to a single pool member as long as it is available. If it fails the persistence record will be replaced with the next incoming connection. This is an alternative to using priority groups. Priority groups may tend to flapping between pool members in case the high-priority member is not stable. Cheers, Stephan
