Hello，Maxim Dounin！

We have a problem about NGINX and hope that you can help us.

We want to transform a file which is being written to. In other words,we want to send one request to NGINX server to download a file which is being written to. And we want to get the complete file finally. We read http/1.1 and knew that the "Transfer-Encoding: chunked " should be used.
But we don't know how to let NGINX know the file is not completed and use " Transfer-encoding: Chunked".

We are looking forward to your reply!

Best wishes,
Irelia
