If your Squid is not compiled with the default internal DNS client
(--disable-interna-dns not used) then the positive_dns_ttl parameter is
not used at all by Squid. Instead the TTL value given by DNS is used.
There is a patch to make Squid-2.5 use this parameter as a upper limit on
DNS TTL for positive caching.

If you build Squid with --disable-internal-dns then DNS TTL information
will not be available to Squid and the positive_dns_ttl will be used.
