trackingServer

The trackingServer variable determines the domain that AppMeasurement uses to send data to Adobe over HTTP. If this variable is not defined correctly, your implementation can experience data loss.

Before the Adobe Experience Cloud Identity Service, this variable also determined where third-party cookies were set. Adobe strongly recommends using the ID service in all implementations where possible.

AppMeasurement uses trackingServer as a fallback if trackingServerSecure is not set. Many older implementations do not set trackingServerSecure, using trackingServer as a fallback on secure pages. With the prevalence of HTTPS, Adobe recommends using trackingServerSecure where possible.
