/**
 * This class provides a response control that may be used to provide the server
 * ID of the Directory Server instance that processed the associated request.
 * For search operations, each entry and reference returned will include the
 * server ID of the server that provided that entry or reference.  For all other
 * types of operations, it will be in the {@code LDAPResult} (or appropriate
 * subclass) returned for that operation.
 * 
*
* NOTE: This class, and other classes within the * {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only * supported for use against Ping Identity, UnboundID, and * Nokia/Alcatel-Lucent 8661 server products. These classes provide support * for proprietary functionality or for external specifications that are not * considered stable or mature enough to be guaranteed to work in an * interoperable way with other types of LDAP servers. *
*
