This property can be used for creating a mapping for more than one host name which may be the case if applications hosted on a server are accessible by more than one host name. This property can also be used to configure Access Manager to not take corrective action for certain URLs. For example, if no redirect is required for users who access applications by using an IP address, this feature can be implemented by specifying a map entry such as:
com.sun.identity.server.fqdnMap[IP address ]=IP address.
If more than one mapping is defined, ensure that there are no overlapping values in the invalid FQDN name. Failing to do so may result in the application becoming inaccessible.
