The origin server is currently testing its communication of tracking status. ? : Dynamic. The origin server needs more information to determine tracking status. G : Gateway or multiple parties. The server is acting as a gateway to an exchange involving multiple parties. N : Not tracking. T : Tracking. C : Tracking with consent. The origin server believes it has received prior consent for tracking this user, user agent, or device. P : Potential consent. The origin server does not know, in real-time, whether it has received prior consent for tracking this user, user agent, or device, but promises not to use or share any DNT:1 data until such consent has been determined, and further promises to delete or permanently de-identify within 48 hours any DNT:1 data received for which such consent has not been received. D : Disregarding DNT. The origin server is unable or unwilling to respect a tracking preference received from the requesting user agent. U : Updated. The request resulted in a potential change to the tracking status applicable to this user, user agent, or device.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
