| 114 =head1 DESCRIPTION | |
| 115 | |
| 116 Базовый класс для ответов приложения на C<HTTP> запрос. Каждый вид ответа, | |
| 117 например | |
| 118 | |
| 119 Данный объект используется для формирования и передачи данных C<HTTP> ответа | |
| 120 напрямую. Основными полями являются C<body> и C<status>. | |
| 121 | |
| 122 Кроме свойств относящихся непосредственно к самому C<HTTP> ответу, данный объект | |
| 123 может содержать свойства относящиеся к процессу обработки запроса, например | |
| 124 механизму формирования представления. | |
| 125 | |
| 126 =head1 MEMBERS | |
| 127 | |
| 128 =head2 C<[get,set]status> | |
| 129 | |
| 130 Статус который будет отправлен сервером клиенту, например, C<200 OK> или | |
| 131 C<204 No response>. Если не указан, то будет C<200 OK>. | |
| 132 | |
| 133 =head2 C<[get,set]type> | |
| 134 | |
| 135 Тип содержимого, которое будет передано клиенту, если не указано, будет | |

| 139 | |
| 140 Кодировка в которой будут переданны данные. Следует задавать если и только, если | |
| 141 передается текстовая информация. Если указана кодировка, то она будет | |
| 142 автоматически применена к потоку, который будет передан методу C<PrintResponse>. | |
| 143 | |
| 144 =head2 C<[get,set]cookies> | |
| 145 | |
| 146 Опционально. Ссылка на хеш с печеньками. | |
| 147 | |
| 148 =head2 C<[get,set]headers> | |
| 149 | |

| 165 Тело ответа. Может быть как простой скаляр, который будет приведен к строке и | |
| 166 выдан в поток вывода метода C<PrintResponse>. Также может быть ссылкой на | |
| 167 процедуру, в таком случае будет вызвана эта процедура и ей будет передан | |
