The Public Suffix List, version d17a65633b0286833727ef21e897a22564695ef5, fetched on 2022-05-23

The Public Suffix List is an initiative of Mozilla, but is maintained as a community resource. It is available for use in any software, but was originally created to meet the needs of browser manufacturers. It allows browsers to, for example:

- Avoid privacy-damaging "supercookies" being set for high-level domain name suffixes

- Highlight the most important part of a domain name in the user interface

- Accurately sort history entries by site

Used in Qt Network to avoid setting "supercookies" in the cookie jar supported by Qt (by the QNetworkCookieJar class).

The sources can be found in qtbase/src/network/kernel/qurltlds_p.h.
