Is it possible to have a nested MultipartEntities or FormBodyPart in a multipart POST?

问题 I need to deliver big files like file.zip (~2 GB) to customers, with a unique URL for each customer. Then I will redirect (with .htaccess ) a customer download link example.com/download/f6zDaq/file.zip to something like example.com/download.php?id=f6zDaq&file=file.zip But as the files are big, I don't want the fact that PHP processes the downloading (instead of just letting Apache handle it) to be a CPU / RAM performance issue for my server.
