No, just IPv4 behind the Squid servers. We run IPv6 on the
outside of Squid, but I don't know if www.tv4play.se uses
any IPv6 in their services.

I discovered today that the production squids (3.1.16) require
forwarded_for delete. The lab squid (3.2 latest as of yesterday)
worked with forwarded_for off, but not the 3.1.16 version.
Strange that it should differ, or is there some way that Squid
3.1 and 3.2 handles this header differently?
