Доброго времени суток!
Решил настроить связку nginx + OHS(OracleIAS10g).
По какой-то причине не корректно работает redirect 301.
Версия nginx 1.8
Смортю в firebug, браузеру приходит ответ c полной ссылкой на http такого вида:
Status: 302 Moved Temporarily
Location: http://example.com/test/index.html?command=refresh2&__sessionId=47&__commandId=51

хотя по идее должна прийти:

Location: httpS://example.com..........

Нашел в интернете, что для настройки такой конфигурации в связке с СП Weblogic12c есть параметры:

# WebLogic:
#proxy_set_header WL-Proxy-Client-IP $_ClientIP_HeaderVariableValue;
#proxy_set_header WL-Proxy-SSL $_SSLChannelFlag_HeaderVariableValue;


Но ничего подобного для OracleIAS10g не нашел....

Конфиг прилагаю:

Почему в итоге возвращается http, а не https?
