NimbostratusF5 GTM Persistence TTL - Is it an Idle Timeout?
When a persistence TTL is configured for GTM, is the TTL computed from the first time a customer visits, or is it computed from the most recent time the customer has visited? I'm concerned about a 3600s TTL timing out on a source IP that is actively making HTTP connections over a 1 hour time period, and GTM flipping the customer over to another pool.
The expires time on the persistence record does not appear to increment with subsequent DNS requests, so I would say it is computed from the first time, not the most recent time.
Generally the larger problem than this is what happens when the client's LDNS changes in the middle of their session? Using Topology or Geo rules would seem a safer method to try and make sure they stay on the same LTM.
