you can not do it. You'd have to restart squid.

Depends which version you use.

For 2.3, with internal DNS lookups, Squid uses the TTL from the
DNS reply. In this case, 'positive_dns_ttl' is not used.

If you have an older version, or are using external dnsserver
lookups without the "DNS_TTL hack", then positive_dns_ttl is used.
