That is the general intention of Squid request forwarding.
Hmm, I still dont get why the child displays the error page when the
parents fails to resolve. I think I will use the workaround with the
line monitoring.
Any opinion about establishing sibling relationship between the backends?
sibling relations does not help the problem you are seeing, but may
improve hit ratio.
Improving the hit ratio is why I want to do this. Are there any best
practices, e.g. icp?
The same improvement in hit ratio for a lower overhead cost can be seen
if you configure the child caches to use carp to select which parent to
use. When using carp the childs always sends the same URL to the same
parent (forwarding selection based on a hash of the requested URL).
I dont think this will improve hit ratios as the the parents are
non-caching ( to slow - ancient Compaq Proliant 1500's ) but this will
IMHO allow load-balancing without the drawback of using round-robin
parents.
I have seen trouble with some webpages as both parents have different
IP'd due to the DSL connection (session based stuff).
Am I right? Will carp stick to one parent depending on the whole url or
just the hostpart?
