OK, I got something that's starting to work.

# Exceptions
EXCEPTIONS=$(egrep -v '(^\#)|(^\s+$)' /usr/local/sbin/no-proxy.txt)
for EXCEPTION in $EXCEPTIONS; do
  $IPT -A PREROUTING -t nat -i $IFACE_LAN -d $EXCEPTION -j ACCEPT
done

# Squid
$IPT -A INPUT -p tcp -i $IFACE_LAN --dport 3128 -j ACCEPT
$IPT -A INPUT -p udp -i $IFACE_LAN --dport 3128 -j ACCEPT
$IPT -A PREROUTING -t nat -i $IFACE_LAN -p tcp ! -d $SERVER_IP \
  --dport 80 -j REDIRECT --to-port 3128
$IPT -A INPUT -p tcp -i $IFACE_LAN --dport 3129 -j ACCEPT
$IPT -A INPUT -p udp -i $IFACE_LAN --dport 3129 -j ACCEPT
$IPT -A PREROUTING -t nat -i $IFACE_LAN -p tcp ! -d $SERVER_IP \
  --dport 443 -j REDIRECT --to-port 3129
$IPT -A INPUT -p tcp -i $IFACE_LAN --dport 3130 -j ACCEPT
$IPT -A INPUT -p udp -i $IFACE_LAN --dport 3130 -j ACCEPT


And here's what the no-proxy.txt file looks like:

# Ne pas utiliser le proxy pour les domaines suivants
#
# Crédit Coopératif
www.credit-cooperatif.coop
# Github
github.com
# Microlinux
microlinux.fr
microlinux.eu
# Squid
squid-cache.org
# Thunderbird
start.thunderbird.net

So far, it works fine.

Any suggestions ?

Niki
