apache and mod_proxy: How can i log which worker was selected?

  • 772

we are runing an apache reverse proxy in front of several tomcats. sometimes we like to know to which server the request was forwarded. as we use mod_proxy_balancer.

i tried 

 \"%{X-Forwarded-Server}i\"

but this doesn't work. it shows the name of my loadbalancer (apache)

How can i log which worker was selected?

logging apache-2.2 load-balancing mod-proxy

    Try %{BALANCER_WORKER_ROUTE}e.

    There's a few other variables available for checking on the request routing, too; see here.
