Is it possible to pass REMOTE_USER as an environment variable using mod_cluster to a JBoss EAP 5.x worker node?

Issue

• AJP connector with mod_jk is being used and REMOTE_USER was passed to JBoss EAP as an Environment Variable. Using mod_rewrite Reference as following:

RewriteCond %{LA-U:REMOTE_USER} (.*)
RewriteRule .* - [E=AJP_REMOTE_USER:%{LA-U:REMOTE_USER}]

• Is it possible to send REMOTE_USER as an environment variable from mod_cluster using AJP to a JBoss EAP5 worker node?
