Re: [squid-users] Problem with parent proxy and no DNS (FATAL: Could not find any nameservers.)

Squid insists on having a DNS server configured, but does not actually
need to use one in such configurations.

Configure squid.conf with

# Fool Squid to think there is a DNS server
dns_nameservers 127.0.0.1

Then make sure you do not use any DNS dependent ACL types, and always
make use of never_direct allow all...
