Re: [squid-users] IPv4/IPv6 fallback

I compiled 3.4.3 from source. This does seem to work now, albeit slow to

I think I should have searched 'squid happy eyeballs' first. Apologies,
finding more details now and reading into it.

(ex: http://www.squid-cache.org/mail-archive/squid-users/201303/0422.html)

FYI - anyone wanting to test any of this, here is a great site:
