Squid3-ipv6 performed its full page load across the IPv4-IPv6 boundary two hours ago!
The goal is within sight, blinking orange icons and all.
It’s still operating with limits. There is a bug apparently in the ipcache that causes it to die a few minutes after starting. Also some unchanged socket logic means IPv4 clients are hamstrung and cannot access IPv6 servers yet. Same thing makes split-stack (win32) a long way off.
Still, even one page load is a large milestone for previously dead code. Google never looked so good.
