By default, nginx does not transmit the "status" and "X-accel-..." headers from the FastCGI server to the client. This parameter can also hide some other headers.
If you must pass the "status" and "X-accel-..." headers, you must use fastcgi_pass_header to force them to be transmitted to the client. Fastcgi_ignore_cli

Different web servers implement different HTTP header sendfile headers.

The disadvantage of using X-SendFile is that you lose control of the file transfer mechanism. For example, if you want to perform some operations after the file is downloaded, for example, you can only download the file on
