Re: Прием не всех POST запросо в, возможно-ли?

["pawel" <nginx-forum@xxxxxxxx>]

Изначально планировал бекендом
создавать файл-маркер с уникальным
именем и в качестве action'а формы
отправки отдавать браузеру, затем, в
идеале, в момент начала приема post'а с
файлом nginx'ом удалять файл-маркер, и
затем nginx отдает форму без тела
принятого файла бекэнду.

Сейчас уперся в:
если файл /file_receiver/secret-marker-file-one.html есть,
принимает, нормально, передает бекэнду,
если файла /file_receiver/secret-marker-file-one.html нет,
не передает, но post запрос все равно
принимает весь полностью.
в идеале отработка  if (!-f $request_filename) { return 
444; }  после приема формы запроса и до
приема части с файлом, если такое
вообще возможно.
вот конфиг:
