A lot of installations are using caching in dnsdist, yes. I don't see
anything immediately wrong after looking at your configuration. What
makes you think caching is not working?

Hi Remi
Thank you for your answer
I test the cache as follows:
getPool("resolverTopnet"):getCache():printStats()
I get empty values:
Entries: 0/2000000
Hits: 0
Misses: 0
Deferred inserts: 0
Deferred lookups: 0
Lookup Collisions: 0
Insert Collisions: 0
TTL Too Shorts: 0
before updating dnsdist from 1.5 to 1.7 i can see the values
Thanks a lot

But how are you testing exactly? How are you sending the DNS queries
during your test?
