| 92 | |
| 93 Обработчик запроса для веб приложения. Загружает шаблон, путь к котрому берется | |
| 94 из C<ENV{PATH_INFO}> относительно пути из свойства C<templatesBase>. | |
| 95 | |
| 96 Наследуется от C<IMPL::Web::QueryHandler> для реализации функционала | |
| 97 обработчика запроса и переопределяет метод C<Process>. | |
