Squid is a WWW Cache application developed by the National Laboratory for Applied Network Research and members of the Web Caching community. Squid is implemented as a single, non-blocking process based around a BSD select() loop. This document describes the ROAD-MAP to port Squid3 into IPv6 and is intended to be used by others who wish to customize or improve it. All code is referring to branch squid3/squid3-ipv6 at CVS
