055/**
056 * This class provides a request control which may be used to request that the
057 * Directory Proxy Server return the backend set IDs for the entry-balancing
058 * backend set(s) in which an operation was processed successfully.  It may be
059 * used in conjunction with the route to backend set request control in order
060 * to specify which backend set(s) should be used to process an operation.
061 * <BR>
062 * <BLOCKQUOTE>
063 *   <B>NOTE:</B>  This class, and other classes within the
064 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
065 *   supported for use against Ping Identity, UnboundID, and
066 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
067 *   for proprietary functionality or for external specifications that are not
068 *   considered stable or mature enough to be guaranteed to work in an
069 *   interoperable way with other types of LDAP servers.
070 * </BLOCKQUOTE>
071 * <BR>
072 * This control may be used for a number of different kinds of requests,
073 * including:
074 * <UL>
075 *   <LI>If an add request includes a get backend set ID request control, the
076 *       add response will include a get backend set ID response control if the
077 *       entry was successfully added to an entry-balanced data set.</LI>
078 *   <LI>If a simple bind request includes a get backend set ID request control,
079 *       the bind response will include a get backend set ID response control if
080 *       the authentication was successful and the entry for the authenticated
081 *       user exists in an entry-balanced data set.  This control is currently
082 *       not supported for use with SASL bind operations.</LI>
083 *   <LI>If a compare request includes a get backend set ID request control, the
084 *       compare response will include a get backend set ID response control if
085 *       the result code is either COMPARE_TRUE or COMPARE_FALSE and the target
086 *       entry exists in an entry-balanced data set.</LI>
087 *   <LI>If a delete request includes a get backend set ID request control, the
088 *       delete response will include a get backend set ID response control if
089 *       the entry was successfully removed from an entry-balanced data
090 *       set.</LI>
091 *   <LI>If an atomic multi-update extended request includes a get backend set
092 *       ID request control and the request is successfully processed through an
093 *       entry-balancing request processor, then the extended response will
094 *       include a get backend set ID response control.  A non-atomic
095 *       multi-update extended request should not include the get backend set ID
096 *       request control in the extended operation itself, but may be attached
097 *       to any or all of the requests inside the multi-update operation, in
098 *       which case the server will return a multi-update response control
099 *       attached to the corresponding successful responses.</LI>
100 *   <LI>If an extended request includes a get backend set ID request control
101 *       and that request is successfully processed by a proxied extended
102 *       operation handler, then the extended response will include a get
103 *       backend set ID response control indicating the backend set(s) that
104 *       returned a success result during internal processing.  Note that if the
105 *       same extended request was processed by multiple entry-balancing
106 *       request processors (i.e., if the deployment includes multiple
107 *       entry-balanced subtrees), then the extended response may include a
108 *       separate get backend set ID response control for each entry-balancing
109 *       request processor used to process the request.</LI>
110 *   <LI>If a modify request includes a get backend set ID request control, the
111 *       modify response will include a get backend set ID response control if
112 *       the entry was successfully modified in an entry-balanced data set.</LI>
113 *   <LI>If a modify DN request includes a get backend set ID request control,
114 *       the modify DN response will include a get backend set ID response
115 *       control if the entry was successfully moved and/or renamed in an
116 *       entry-balanced data set.</LI>
117 *   <LI>If a modify DN request includes a get backend set ID request control,
118 *       the modify DN response will include a get backend set ID response
119 *       control if the entry was successfully moved and/or renamed in an
120 *       entry-balanced data set.</LI>
121 *   <LI>If a search request includes a get backend set ID request control, any
122 *       search result entries retrieved from an entry-balanced data set will
123 *       include a get backend set ID response control.  The search result done
124 *       message will not include a get backend set ID response control.</LI>
125 * </UL>
126 *
127 * Note the response for any operation involving an entry that exists outside of
128 * an entry-balanced dat set will not include a get backend set ID response
129 * control.  Similarly, the response for any non-successful operation may not
130 * include a get backend set ID response control even if it involved processing
131 * in one or more backend sets.  Also note that even if an entry exists in
132 * multiple backend sets (i.e., because it is at or above the balancing point),
133 * the get backend set ID response control may only include one backend set ID
134 * if only one backend set was accessed during the course of processing the
135 * operation.
136 * <BR><BR>
137 * The get backend set ID request control has an OID of
138 * "1.3.6.1.4.1.30221.2.5.33" and no value.  It is recommended that the control
139 * be non-critical so that the associated operation may still be processed even
140 * if the target server does not support this control (and note that even if
141 * the server supports the control, the server may not return a response control
142 * if the operation was not successful or did not access entry-balanced data).
