178 Возобновляет сессию пользователя на основе информации переданной через Cookie.
|

179
|
|
|
180 Использует механизм подписи информации для проверки верности входных данных перед
|
|
|
181 началом каких-либо действий.
|
|
|
182
|
|
|
183 Данный обработчик возвращает результат выполнения следдующего обработчика.

195
|
|
|
196 Инициирует сессию, поскольку данный модуль отвечает за взаимодействие с клиентом
|
|
|
197 при проверки аутентификации, ему передаются данные аутентификации для
|
|
|
198 продолжения обмена данными с клиентом. Если создается новая сессия, по
|
|
|
199 инициативе веб-приложения, то C<$auth> должно быть пусто.
