If that is your actual need, then simply not adding dns_nameservers
directive in squid.conf is the answer. The system DNS resolver settings
will be loadeed from /etc/resolv.conf *unless* you manually specify
values in squid.conf.

Then src/cf.data.pre is what you want. Look in there for "DEFAULT:" lines.

Your previous posts on this topic indicated that your purpose was to
*hide* some information from your users. As you were old back then, this
is the wrong way to go about it. For two very critical reasons:

1) default settings built into Squid can be viewed by anyone able to
access the machine simply by using "squid -k parse" with verbose or
debug flags.


2) Modified binaries are required to comply with the GPL version 2
license. If anyone requests to see the modified version of your source
code you are required to deliver it in sufficient form for them to be
able to build ther own binary identical to yours.
