[#12216] - Http 503 with haproxy

Hi

I'm using 2 JasperReport servers on windows with Haproxy (1.5.18).
The proxy receive an http 503 if i use the check option.
The old version of jasper server (6.3.0), works well with the check option of the proxy.

backend jasperreport-backend
balance roundrobin # Load Balancing algorithm
option httpchk
option forwardfor except 127.0.0.0/8
server jasper_1 192.168.10.142:8080 weight 10 maxconn 512 check
server jasper_2 192.168.10.143:8080 weight 10 maxconn 512 check

Any idea to resolve the problem?

Thanks

M.
