[squid-users] high latency satellite link - downloads slow/cease, broken links

before i get started, do note that bypassing the proxy, everything is fine.

Ive used squid without a hitch for years now, but never on a
satellite. On sites with a lot of links or images (news sites,
hardware reviews, p*rn, hell any modern site) it will break a LOT of
the links to pictures/background images/etc. Basically after a week
of trying every directive ive ever used and then some, i cant make it
any better. putting the dns_servers 127.0.0.1 helped in a way: it
made the sites begin to load faster, but the broken links were still
there. I basically got nowhere faster with that one. nothing else
ive tried seems to phase it. im not sure if there's any OS tweaks
that should be done at this point or if im SOL.

ANY help/person with experience with this would be greatly
appreciated. we're a lowly cold (and remote!) little air force base
that needs all we can get in our barracks!
