[squid-users] Skip IP6 addresses

Hello,

Is it possible to set up squid 3.1.6 so that it wouldn't use IP6
addresses when proxies requests.

Specifically I can't access http://packages.debian.org because squid
tries to do so with an IP6 address an I have only IP4 connection to the
Internet:

The following error was encountered while trying to retrieve the URL:
http://packages.debian.org/search?

     Connection to 2001:648:2ffc:deb:214:22ff:feb2:17e8 failed.

The system returned: (110) Connection timed out

The remote host or network may be down. Please try the request again.

However packages.debian.org has IP4 addresses as well:

# host packages.debian.org
packages.debian.org has address 87.106.64.223
packages.debian.org has address 128.31.0.49
packages.debian.org has address 194.177.211.202
packages.debian.org has IPv6 address 2001:8d8:81:1520::1
packages.debian.org has IPv6 address 2001:648:2ffc:deb:214:22ff:feb2:17e8
packages.debian.org mail is handled by 10 powell.debian.org.
