Description

PublicSuffixList provides the public suffix of a domain. For example:

- the public suffix of "example.com" is "com",
- the public suffix of "foo1.foo2.foo3.co.uk" is "co.uk", and
- the public suffix of "bar.pvt.k12.ma.us" is "pvt.k12.ma.us".

Implementations of PublicSuffixList must be safe for concurrent use by multiple goroutines.

An implementation that always returns "" is valid and may be useful for testing but it is not secure: it means that the HTTP server for foo.com can set a cookie for bar.com.

A public suffix list implementation is in the package golang.org/x/net/publicsuffix.
