| 69 | |
| 70 Зкземпляр приложения содержит в себе глобальные настройки, реализует контроллер запросов, | |
| 52 | 71 в качестве источника запросов используется CGI или иной совместимый модуль. |
| 49 | 72 |
| 52 | 73 Процесс обработки запроса состоит из следующих частей |
| 49 | 74 |
| 52 | 75 1. Получение cgi запроса |
| 76 2. Вызов модуля для инициализации объекта действия | |
| 77 3. Инициализация контекста выполнения | |
| 78 4. Выполнение запроса | |
| 79 5. Преобразование полученных данных в тело ответа | |
