HttpHealthcheckModule server not marked down

[Sjaak Pieterse]

Hey Liseen,

Thank you for teh fix, it's working now for standard round robin, for
upstream_hash it's not working but that's no problem for us we are not
using that in production.
what we often use is gnosek-nginx-upstream-fair, to make it work with
that, can you tell how to handle?



this is what i've done to make it work for now:
