iRule for HTTP::cookie creation works once on the first login. Any login after that no cookie is created

I see that you posted in the other ducussion. While you wait you can add log local0 after HTTP RESPONSE to see if the HTTP response is at all triggered for the next clients after the first one. Also a log local0 after ACCESS::session data get session.custom.suppressmfa.setauthtable but before table set and log local after the table set .My idea is if possible to see where it breaks in the LTM log.

Also as I mentoned check in the F5 ihealth for under diagnostics if any bugs are detected for the commands that this irule worked and also check the ltm log for TCL error. It is possible after the upgrade a bug to be hit or irule command to have been removed. What was you previous version before this?
