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.
Probably the "wrong" status code is returned by the parent in this situation, or it takes too long. The child only retries if there is time left before the request times out..
Improving the hit ratio is why I want to do this. Are there any best practices, e.g. icp?
Depends on the number of caches you have, and how you distribute the clients among the caches..
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).
CARP will still show the same symtoms. CARP is sticky per complete URL, not just the host part.
