Я очень заинтересован в том, чтобы найти ошибку на веб-сервере или определить, есть ли у ab проблема

здесь вывод от сеанса telnet, имитирующего ab

Таким образом, проблема заключается в том, что спецификация требует 0 CRLF CRLF в качестве конечного маркера фрагментированного кодирования передачи.ab не работает, потому что он хочет 0 и CRLF.

Из этого вывода похоже, что есть дополнительный CRLF после заголовков второго ответа, тогда как ab ожидал бы увидеть длину фрагмента.
