Connect directly if parent cache fails

[Tom Tux <tomtux80@xxxxxxxxx>]

Hi

I'm trying to configure Squid (3.1.9) to connect directly, if the one
and only cache_peer (parent) fails:

cache_peer xx.xx.xx.xx parent  8080            0       no-query
no-digest default connect-fail-limit=5
prefer_direct off
never_direct allow all


But squid will never connect directly, even if the parent isn't
available. How can I implement this?

Thanks a lot.
Tom
