public final class ServerAcl extends Object
The ACL file is reloaded whenever a modification to it is detected. If you copy in a file with an older file date, you will need to touch it.
The public runtime method is permitAccess(). The public setup method is the constructor.
Each non-comment line in the ACL file must be a rule of the format:
     {allow|deny} <ip_address>[/significant-bits]
 
     allow ahostname
     deny ahost.domain.com
     allow 127.0.0.1
     allow 2001:db8::/32
 In order to detect bit specification mistakes, we require that non-significant bits be zero in the values. An undesirable consequence of this is, you can't use a specification like the following to mean "all of the hosts on the same network as x.admc.com":
     allow x.admc.com/24
