mod_cluster only resolves hostname of proxy once at start up

Issue

• We configure mod_cluster with a static proxy (no advertise) by the proxy's hostname. Our httpd proxy is in a dynamic environment where its hostname could change to resolve to a new ip address across httpd restarts. But we see JBoss only resolves the proxy hostname once at start up so it can never resolve the host again to re-connect to the new httpd ip after httpd has any restart and ip change. Can mod_cluster have a way to resolve the host name again?
