Usage: Behavior tracking; This is being used for the same purpose as the first cookie(79f08280-5c63-4331-b04d-fb6f39afda51). Only difference is that this cookie is set on the customer domain. In some cases, we’re unable to access third party cookies (ex: safari OOB blocks) therefore we set this first party cookie to keep functionality.
