Varni sh -4 всегда возвращает x-cache: pass uncacheable

Question

Я сейчас настраиваю Varni sh 4 для моего домена для пост-запроса. Но я не могу понять, почему запрос всегда «MISS», и я получаю x-cache как passcacheable.

Как вы видите Отладка: "XXX HIT-FOR-PASS"

Это всегда происходит, даже если на бэкэнд-сервере установлен Cache-Control: publi c, max-age = 86400

Varni sh, конечная точка возвращает x-cache: pass uncacheable

Первый ответ 411 Требуется длина, тогда как последующий ответ успешен с 200 OK, но с X-Cache как «pass uncacheable».

Что я делаю неправильно?
