* This class provides a response control that may be used to provide the server

* 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 is part of the Commercial Edition of the UnboundID
* LDAP SDK for Java. It is not available for use in applications that
* include only the Standard Edition of the LDAP SDK, and is not supported for
* use in conjunction with non-UnboundID products.
*
*
* This control must have a value, which will simply be the string
* representation of the server ID of the associated server. The criticality
* should be {@code false}.
