Registry-Controlled Domain Service

This directory contains Chromium's copy of the Public Suffix List and utilities for accessing it. This is useful for callers who need to understand what the eTLD ("effective Top-Level Domain") + 1 is for some hostname, which in turn is necessary to determine things like "this host should be allowed to read/write cookies from this other host".
