My bad, I didn't figure out you were talking about 503s from the
backend (as opposed to eg. connect errors which are handled as
internal 503s).
AFAICT recovering from backend error is not reliably feasible, non
idempotent requests (eg. POSTs) cannot be re-sent by a proxy.

hhmmm i'm not experiencing that.
i've got a php script on the back end that send a 503 header:
NODE1
<?php
header('HTTP/1.1 503 Service unavailable');
echo "error";
?>
NODE2
<?php
echo "ok";
?>
But when i make requests on the cluster i get 50% of "error" and 50% of
"ok".

Hi,
this is an implicit behaviour.
Regards,
Yann.
