Hi, I've setup two frontends balanced with Haproxy 1.3.15.7 (excellent software) in another server:
Load balancer / \ / \ / \ Frontend 1 Frontend 2 I have enabled "option forwardfor". I have set LogFormat in Apache configuration file as follows: LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined but many times the IP field appears empty. I've read on this mailling list that it has something to do with KeepAliveTimeout on Apache. I rised up it from 6 to 15, but no luck. How could I fix this? Thank you
