Re: Strange squid behavior

Dear Duane,

My problem is that we have a single nonreliable link between Chernogolovka
and Moscow. I have a squid cache on both ends of this link, and I would like
to receive information only via parent cache on another end.
Of course, I can switch firewall off and permit single_parent_bypass
but I would non like to do this.

In my case, the main reason of failure when querying parent is not due to
parent cache failure but due to link faulure, and permitting single parent
bypass will produce no results.

Is it possible that squid automatically swithch off parent cache if it is
non accessable during a period of time, and this switch remains to be off
when parent becames accessible after line reparing ?

I'll try to apply this patch and see the results.
