A zombie cookie is data used to track users while they browse websites. Like a regular HTTP cookie, it is created by a web server and placed on a user's computer or other device through the web browser. It can be stored in multiple locations, allowing it to be recreated if not all copies are removed. It may continue recreating deleted cookies even when a user has opted not to receive cookies.
