/**
 * This class provides a request control which may be used to request the server
 * ID of the server that actually processed the associated request.  It may be
 * used for requests sent directly to a Directory Server, but it is more useful
 * when the request will pass through a Directory Proxy Server instance because
 * the corresponding {@link GetServerIDResponseControl} will provide the server
 * ID of the backend server used to process the request.  This server ID may be
 * used in a {@link RouteToServerRequestControl} instance to request that
 * subsequent operations be processed by the same server.  See the documentation
 * for the {@code RouteToServerRequestControl} for an example that demonstrates
 * this.
 * 

 * 

 *   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.
 * 
 * 

 * This control does not have a value.  The criticality may be either
 * {@code true} or {@code false}.
