89 Отвечает за инфраструктуру аутентификации и авторизации запросов. Основная особенность
wizard
parents: 66
diff changeset
90 заключается в том, что запросы приходят через значительные интевалы времени, хотя и
wizard
parents: 66
diff changeset
91 относятся к одной логической транзакции. В промежутках между запросами сервер не
wizard
parents: 66
diff changeset
92 сохраняет свое состояние. Поэтому при каждом обращении сервер восстанавливает
wizard
parents: 66
diff changeset
93 контекст безопасности.
