Failover on HTTP 500 error

[Martin Cizek <martin@xxxxxxxxx>]

Hi all,

        we're using Squid as a web accelerator of GET-based queries to
an intranet system. The intranet system consists of two nodes (mutual
backup) and there is a DNS entry with two "A" records pointing to them.
Everything goes perfectly if a node is unreachable or refuses
connections - the other one is tried by Squid.

        But - is it possible to force Squid to try the other node if the
fist node accepts connection and returns HTTP status 500 (possibly using
a patch)?

Thanks in advance,
                    Martin Cizek
