A Set-Cookie command appears for an ASM cookie (TS cookie) where the value has not changed and the set-cookie command is not needed.
The unneeded cookie may disturb caching and cause additional unnecessary bandwidth consumption.
-- The policy building is automatic or manual mode. -- Additional features may also cause TS cookie setting, but usually these will also include cookie changes.
If possible, turn off the policy builder.
