This answer is incorrect because Squid has its own DNS cache. Squid pays attention to DNS record TTLs. I believe there are several bugs in that code, but, in many cases, Squid will not cache the answer for less than negative_dns_ttl and for longer than the minimum of the received TTL and positive_dns_ttl. DNS answers may be purged from the Squid DNS cache for reasons other than TTL, of course. >> how can i put more time to live? > You cannot (and should not). One can increase effective TTL in Squid DNS cache by increasing negative_dns_ttl. Whether one _should_ do that is a different question that I cannot answer in general.
