I suggest reporting a bug if you can reproduce with the latest v4 release. Posting a (link to) compressed ALL,9 cache.log to bugzilla may speed up triage. FWIW, using v5-based code, your test worked for me with an immediate ERR_CANNOT_FORWARD error and the following level-1 cache.log entry: 2019/01/14 09:04:58| DNS error while resolving de.sitestat.com: No valid address records Alex. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
