[dnsdist] cache dnsdist not working for my setup

Hello
I'm sorry OTTO, but I'm pressed for time as soon as I migrated to version 1.5 I encountered quite a few problems!
now I only have the problem of log (empty) and the cache which still does not work

----------Log config------------------------------
-- log all queries to a 'dndist.log' file, in text-mode (not binary) appending and unbuffered
addAction(AllRule(), LogAction("/var/log/dnsdist/dnsdist.log", false, true, false))

-------------------------Cache config-------------------------
ewServer({name="unbound",pool={"resolverT"},address="IP", qps=1000, order=1})
newServer({name="pdns-recursor",pool={"resolverT"},address="IP", order=2})
cacheresolv = newPacketCache(100000)
getPool("resolverT"):setCache(cacheresolv)
setStaleCacheEntriesTTL(86400)
addAction(AllRule(), PoolAction("resolverT"))

When swicthing versions, it is very important to read the upgrade
guide (and other docs) first. Also read and understand
https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/

Only if you think for yourself first and give complete information to
the list we can maybe help you. At the moment, your messages only
cause noise on the list.
