Adobe collects data on your site by receiving an image request generated by the visitor. The trackingServerSecure variable determines the location an image request is sent over HTTPS.

The s.trackingServerSecure variable is a string that contains the location to send image requests. It is almost always a subdomain of your site. Modern privacy practices in browsers commonly make third-party cookies unreliable. If this variable is blank, it uses the value in the s.trackingServer variable.

The value for this variable is almost always a first-party domain, such as See First-party cookies in the Experience Cloud in the Core Services user guide for more information on the first-party cookie process.

The individual who initially configures the first-party cookie implementation also defines the domain and subdomain used. For example:

s.trackingServerSecure = "";

CNAME records usually point to a subdomain on, or
