Setting the policy lets you make a list of URL patterns that specify sites that can't set cookies. Leaving the policy unset results in the use of DefaultCookiesSetting for all sites, if it's set. If not, the user's personal setting applies. While no specific policy takes precedence, see CookiesAllowedForUrls and CookiesSessionOnlyForUrls. URL patterns among these 3 policies must not conflict. For detailed information on valid url patterns, please see https://cloud.google.com/docs/chrome-enterprise/policies/url-patterns. * is not an accepted value for this policy.
