I'm using Apache/2.4.27
Within the VirtualHost I'm forwarding the remote client IP header from the Loadbalancer with:
RemoteIPHeader X-Forwarded-For
Which is needed by the application served by that Virtualhost.
This is the log format within the main httpd.conf context.
LogFormat "%h (%{X-Forwarded-For}i) %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
When I have the RemoteIPHeader X-Forwarded-For
listed within the virtualhost, Apache stops writting the remote-client IP into logs.
When I remove it from the VirtualHost, the remote-client IP starts appearing again within the logs.
Any ideas ?
Thanks !
