My use-case (reason for me using this feature): I want to embed the server in our systems
using a proxy from another Jetty instance with LDAP authentication. The webui should be accessible
to our dev team while the API only accessible from authenticated networks (i.e., no authentication
is used from ACE, iptables filtering allows only some interfaces to connect to ACE, only one
entry point for all our development and admin tools)
