"option httpchk" is reporting servers as down when they're not

[Allen, Thomas]

Hi,
 
I like the idea of having HAProxy check server health, but for some
reason, it reports all of my servers as down. Here's my full config:
 
listen http_proxy :80
    mode http
    balance roundrobin
    option httpchk
    server webA {IP} cookie A check
    server webB {IP} cookie B check
 
I tried "option httpchk /index.php" just to be sure, and got the same
result. If I remove the httpchk option, HAProxy has no problem proxying
these servers. What am I doing wrong?
 
Thanks,
