[squid-users] Recent Squid 4 versions show ERR_CANNOT_FORWARD instead of ERR_DNS_FAIL

[Christof Gerber]

I am wondering why the recent Squid4
(v4-57a5679bae20e90ef73473e03327e37aa0263570) with a minimal config,
when accessing a non-existing domain (e.g.
http://fsdafasdfsadfklsdj.ch/) produces a ERR_CANNOT_FORWARD error
when the older Squid4 (v4-6d8f397398995c4512cb045920ee2747cc6b14f8)
produces a ERR_DNS_FAIL as it is also the case for Squid 3.5.

Why does this different behaviour occur?
Is it a bug or is it a feature?

Ps. Squid 4 v4-9d6a91ba608acadb9f3cb397d72748a711db3c91 is still
producing ERR_DNS_FAIL.
