So my question is... a more direct and precise question, just about ufdbGuard. While ufdbGuard
reloads its URL database, does it pauses answering queries ? If yes, how long does it takes ?
ufdbGuard does not pause answering queries from Squid during a reload since that would pause Squid
and is considered an interruption of service.
ufdbGuard releases the current URL database, loads a new configuration and loads a new URL database
in 10 seconds on average.
ufdbGuard has a configurable behaviour in this 10-second interval and does either one of:
- allow all URLs; send immediately an "OK" back to Squid (default)
- allow all URLs but also introduce artifical delays when sending replies back to Squid.
The effect is that traffic is slowed down and the total number of unfiltered URLs is reduced.
- deny all URLs; send immediately and "not OK" back to Squid. The end user receives a message like
"try again in a few moments".
Yes, there IS an "interruption of service" because during 10 seconds ufdbGuard doesn't work as it
should do : URL filtering based on the URL database.
You should use "degraded service" instead of "interruption of service".
