Hello all,

For a specific need, I want to reduce the DNS requests, so I'm trying with

positive_dns_ttl 6 hours
negative_dns_ttl 4 hours

But there is something wrong

If I try a false domain like test.google.com there is a response from my DNS Servail, so ok 
But if I retry after a short time - maybe one minute - there is again a DNS request  

Same thing with positive_dns_ttl, Squid respects the TTL from DNS

As far as I can tell, there is no change with or without DNS options
