problem with forwardfor option

Hi,

I am running haproxy (HA-Proxy version 1.3.15.7 2008/12/04) and I am having problems with the forwardfor option. In particular I am seeing about 50% of the requests leave haproxy and hit the apache server behind in without an X-Forwarded-For header. I am not sure whether the problem is a bug or a misconfiguration. Here is my config:

global

         log 127.0.0.1   local0
         maxconn 10000
         chroot /usr/share/haproxy
         pidfile /var/run/haproxy.pid
         user haproxy
         group haproxy
         daemon

defaults
         mode       http
         retries    3
         clitimeout 150000
         srvtimeout 30000
         contimeout 4000
         option     redispatch

listen  webproxy :80
         mode      http
         log       127.0.0.1   local0
         reqidel   ^X-Forwarded-For:\
         reqadd    X-Worio-FE:\ 10.251.163.95
         option    forwardfor
         balance   roundrobin
         server    fe1 10.251.163.95:8080

# HTTP response : 'HTTP/1.0 200 OK'
listen http_health_check 0.0.0.0:60001

         mode health
         option httpchk

any ideas as to what could be wrong?

Thanks!
