That smells more like a tcp windows issue than an HTTP/1.1 issue..

If on Linux try the following workaround:

echo 0 >/proc/sys/net/ipv4/tcp_window_scaling

this works around quite many broken firewalls not coping well with
window scaling, but significantly scarifies performance over long
distance connections (measured in RTT * bandwidth, not miles)...

For what it's worth I had no problem loading the start page using
Firefox via Squid-2.

Testing.. Ah, yes. There is a broken firewall at this site crashing
window scaling..

Someone should contact the site operators explaining the problem to
them..
