Abstract: A system and method for managing the delivery of targeted content. When a user desires to opt-out of receiving targeted content, the user registers with a do-not-target (DNT) registry and is issued a DNT cookie. The DNT cookie is a domain cookie that is stored on a user network access device. A provider of targeted content may look for the DNT cookie stored on the user's network access device. When the DNT cookie is not found, then the provider may deliver targeted content to the user. When the DNT cookie is found, then the provider may not deliver targeted content to the user. A Web site may offer the user an “override” cookie that allows that Web site to provide targeted content, or selected targeted content, even when the user has a DNT cookie. Alternatively, a DNT header can be added to a Web page request that indicates that the user does not want to receive targeted content. The DNT header may be overridden by an override cookie.
