Description

Hello,
I have a setup where I have the Nginx server and application server running on different user accounts. I want to be able to use client_body_in_file_only/client_body_temp_path in order to save the file to disk and forward the $request_body_file to the application. However the file permissions are always 0600 making the application unable to read the file at all.
Looking in the Nginx source code - this is currently an unsupported scenario: https://github.com/nginx/nginx/blob/1305b8414d22610b0820f6df5841418bf98fc370/src/http/ngx_http_request_body.c#L468 creates the temporary file with the default permissions which get later expanded to 0600 (unless request_body_file_group_access is set - but unfortunately that property is not settable).
