It's not necessary for the main Squid cluster to
support IPv6 in order
to serve the main website via IPv6.
The amount of IPv6 traffic will presumably be very small in the short
term. We can just set up a single proxy server in each location (Tampa
and Amsterdam), and point all of the relevant AAAA records to it. All
the proxy has to do is add an X-Forwarded-For header, and then forward
the request on to the relevant IPv4 virtual IP. The request will then
be routed by LVS to a frontend squid.
That's so obvious I'm embarassed I didn't think of it.
Given how big we are, though "very" small may be most websites "medium
traffic
day". :-)
