sergey
parents:
diff changeset
101 например
sergey
parents:
diff changeset
102
sergey
parents:
diff changeset
103 Данный объект используется для формирования и передачи данных C<HTTP> ответа
sergey
parents:
diff changeset
104 напрямую. Основными полями являются C<body> и C<status>.
sergey
parents:
diff changeset
105
sergey
parents:
diff changeset
106 Кроме свойств относящихся непосредственно к самому C<HTTP> ответу, данный объект
sergey
parents:
diff changeset
107 может содержать свойства относящиеся к процессу обработки запроса, например
sergey
parents:
diff changeset
108 механизму формирования представления.
