| 75 | |
| 76 Зкземпляр приложения содержит в себе глобальные настройки, реализует контроллер запросов, | |
| 52 | 77 в качестве источника запросов используется CGI или иной совместимый модуль. |
| 49 | 78 |
| 52 | 79 Процесс обработки запроса состоит из следующих частей |
| 49 | 80 |
| 52 | 81 1. Получение cgi запроса |
| 82 2. Вызов модуля для инициализации объекта действия | |
| 83 3. Инициализация контекста выполнения | |
| 84 4. Выполнение запроса | |
| 85 5. Преобразование полученных данных в тело ответа | |
