CLASSIFICATION::app iRule command does not return any results after upgrade.
CLASSIFICATION::app iRule command will not return any result
This occurs on iRules using CLASSIFICATION::app in BIG-IP 11.5.x and then upgrading to 11.6.0 through 12.0.0.
CLASSIFICATION::app is deprecated. Correct command to use is CLASSIFICATION::result which returns an array of matched applications Sample Usage: when CLASSIFICATION_DETECTED { set res [CLASSIFICATION::result] log local0.debug "classification results: $res" }
CLASSIFICATION::result command was implemented
