Hello Remi
yes it's weird, because in the web interface it says that the cache is working,
here is my configuration
-- == Generic Configuration ==
setACL("0.0.0.0/0")
-- https://dnsdist.org/guides/console.html
controlSocket("127.0.0.1")
-- setKey("please generate a fresh private key with makeKey()")
addLocal("IPServer:53")
setLocal("0.0.0.0:53")
----------------- Mes serveurs ------------------------
newServer({name="unbound",pool="resolverTopnet", address="IPserver1", qps=2000,
order=1})
newServer({name="pdns-recursor",pool="resolverTopnet", address="IPserver2",
order=2})
-------------------------------------------------------cache
-----------------------
setPoolServerPolicy(leastOutstanding, "resolverTopnet")
pc = newPacketCache(2000000, {maxTTL=43200, minTTL=0,temporaryFailureTTL=60,
staleTTL=60, dontAge=false})
getPool("resolverTopnet"):setCache(pc)
addAction(AllRule(), PoolAction("resolverTopnet"))
-----------------------------------------------Begin security rule
------------------------------------------
local dbr = dynBlockRulesGroup()
dbr:setQueryRate(250, 10, "Exceeded query rate", 20)
dbr:setRCodeRate(DNSRCode.NXDOMAIN, 20, 10, "Exceeded NXD rate", 60)
dbr:setRCodeRate(DNSRCode.SERVFAIL, 20, 10, "Exceeded ServFail rate", 60)
dbr:setQTypeRate(DNSQType.ANY, 5, 10, "Exceeded ANY rate", 180)
--dbr:setResponseByteRate(1000, 10, "Exceeded resp BW rate", 60)
function maintenance()
dbr:apply()
end
addAction(MaxQPSIPRule(100), DropAction())
addAction(MaxQPSIPRule(50, 24, 64), DropAction())
addAction({"nl.", "be."}, QPSAction(1))
---------------------------------------------------End security

The cache hitrate information from that output indicates that the cache
is working.
If you still think this is not the case, please share an unedited
configuration that we can use to reproduce the issue, and what you do
exactly to test whether the cache is working.
