Who can access cookies?Last Updated: October 14, 2019
When a cookie is created, it is possible to control its visibility by setting its ‘root domain’. It will then be accessible to any URL belonging to that root. For example, the root could be set to “cookiepro.com” and the cookie would then be available to sites in “www.cookiepro.com” or “cookiepro.com”. This might be used to allow related pages to ‘communicate’ with each other. By default, cookies are visible to all paths in their domains, but at the time of creation they can be restricted to a given sub-path.
