 Currently, you can list the contents of the {{/static}} directory for the RM, NM, and JHS.
 This isn't a huge deal, but there are some ways to abuse this to get access to files on the
host, though it would be pretty difficult.  It's also good practice to disable directory listing
on web apps.
> Here are the URLs:
> - http://HOST:8088/static/
> - http://HOST:19888/static/
> - http://HOST:8042/static/
