80 =head1 DESCRIPTION
sergey
parents:
diff changeset
81
sergey
parents:
diff changeset
82 Базовый класс для ответов приложения на C<HTTP> запрос. Каждый вид ответа,
sergey
parents:
diff changeset
83 например
sergey
parents:
diff changeset
84
sergey
parents:
diff changeset
85 Данный объект используется для формирования и передачи данных C<HTTP> ответа
sergey
parents:
diff changeset
86 напрямую. Основными полями являются C<body> и C<status>.
sergey
parents:
diff changeset
87
sergey
parents:
diff changeset
88 Кроме свойств относящихся непосредственно к самому C<HTTP> ответу, данный объект
sergey
parents:
diff changeset
89 может содержать свойства относящиеся к процессу обработки запроса, например
sergey
parents:
diff changeset
90 механизму формирования представления.

106 Кодировка в которой будут переданны данные. Следует задавать если и только, если
sergey
parents:
diff changeset
107 передается текстовая информация. Если указана кодировка, то она будет
sergey
parents:
diff changeset
108 автоматически применена к потоку, который будет передан методу C<PrintResponse>.

121 Тело ответа. Может быть как простой скаляр, который будет приведен к строке и
sergey
parents:
diff changeset
122 выдан в поток вывода метода C<PrintResponse>. Также может быть ссылкой на
sergey
parents:
diff changeset
123 процедуру, в таком случае будет вызвана эта процедура и ей будет передан
sergey
parents:
diff changeset
124 первым параметром поток для вывода тела ответа.
