Revert to legacy SameSite behavior for cookies on these sites

Cookies set for domains matching these patterns will revert to legacy SameSite behavior. Reverting to legacy behavior causes cookies that don't specify a SameSite attribute to be treated as if they were "SameSite=None", and removes the requirement for "SameSite=None" cookies to carry the "Secure" attribute. See https://www.chromium.org/administrators/policy-list-3/cookie-legacy-samesite-policies for full description.

For cookies on domains not covered by the patterns specified here, or for all cookies if this policy is not set, the global default value will be used either from the LegacySameSiteCookieBehaviorEnabled policy, if it is set, or the user's personal configuration otherwise.

Note that patterns you list here are treated as domains, not URLs, so you should not specify a scheme or port.

Example value:

www.example.com
[*.]example.edu

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
