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)
