[Unbound-users] Testing unbound, cache-max-ttl = 0?

Hi,

We're trying to run some tests on our systems which use unbound. We had an 
upstream recursive server fail the other day - which caused a lot more 
problems than we were expecting (as we use unbound on local machines, 
forwarding to two recursive servers).

At this stage we think it's either a config / timeout issue (i.e. nothing 
wrong with unbound) - but we want to test further.

Can you set 'cache-max-ttl: 0' in unbound.conf, to turn off caching?

During our tests we don't want unbound using cached replies to queries - we 
want to force it to go to the upstream recursive servers every time.

Thanks,

-Karl
