I saw the announcement but it looks like Nginx 1.1.11 isn't still honoring the DNS ttl or the "valid" parameter at all.

I have 2 related questions to this topic

1) Is the following configuration correct to get the resolver "resolving" at least every 5 secs?

location /mylocation {
resolver 127.0.0.4 valid=5s;
set $myserver "myserver:1000";
proxy_pass http://$myserver;
proxy_redirect http://myserver.mydomain.in:8000 https://www.myserver.com;
}

2) If I receive 100 request in 50 seconds and have my DNS (127.0.0.4) returning records with TTL=1. How many request to my DNS should Nginx perform in that period?
