Using mod_cluster and static proxy at the same time on Undertow does not work

Issue

• I currently have a JBoss domain cluster with several back-end servers balanced with Undertow mod_cluster. Is it possible to configure Undertow's static proxy so one of the web services endpoints (/myapp/myep) is directed to a particular server without modifying the war packaging nor the deployment? I've tried the standard setup but the server seems to ignore the static proxy.
