* @remarks
|
||
|
* A "public suffix" is a domain that is controlled by a
|
||
|
* public registry, such as "com", "co.uk", and "pvt.k12.wy.us".
|
||
|
* This step is essential for preventing attacker.com from
|
||
|
* disrupting the integrity of example.com by setting a cookie
|
||
|
* with a Domain attribute of "com". Unfortunately, the set of
|
||
|
* public suffixes (also known as "registry controlled domains")
|
||
|
* changes over time. If feasible, user agents SHOULD use an
|
||
|
* up-to-date public suffix list, such as the one maintained by
|
||
|
* the Mozilla project at http://publicsuffix.org/.
|
||
|
* (See {@link https://www.rfc-editor.org/rfc/rfc6265.html#section-5.3 | RFC6265 - Section 5.3})
|
||
|
*
|
||
|
* @example
|
||
|
* ```
|
||
|
* getPublicSuffix('www.example.com') === 'example.com'
|
||
|
* getPublicSuffix('www.subdomain.example.com') === 'example.com'
|
||
|
* ```
|
||
|
*
|
||
|
* @param domain - the domain attribute of a cookie
|

|
* @param options - optional configuration for controlling how the public suffix is determined
