021/**
022 * Exception representing an HTTP 410 ().
023 *
024 * <p>
025 * Indicates that the resource requested is no longer available and will not be available again.
026 * <br>This should be used when a resource has been intentionally removed and the resource should be purged.
027 * <br>Upon receiving a 410 status code, the client should not request the resource in the future.
028 * <br>Clients such as search engines should remove the resource from their indices.
029 * <br>Most use cases do not require clients and search engines to purge the resource, and a <js>"404 Not Found"</js> may be used instead.
