When acknowledging a cookie or port, you can select the option to Confirm Changes. If this is selected, we’ll remove the acknowledgment if the value changes in a subsequent scan. You’ll be able to see the value of the cookie/port that was acknowledged previously and re-acknowledge the cookie once you are confident it is accounted for. You should avoid setting the Confirm Changes for any cookies or ports that are designed to be static such as authentication cookies and should set this for cookies/ports whose value changes or might change over time.
