Thanks for your reply.

I tried squid2.6 and it works as per requirement . Squid will stop
sending request to origin if origin returns http status code is other
than 2xx.

cache_peer parent 80 0 no-query originserver round-robin
monitorurl=/healthcheck.gif monitorinterval=1

Not sure how difficult it is to port it to squid3 as it is already
supported in squid2.6. We will take a look at code and see if we
could port it to squid3.
