Nginx sends static files at extremely fast speeds. The x-sendfile mechanism in Nginx relies on the X-Accel-Redirect feature. However, after my tests, it cannot meet my needs, I want to use lua to process the business logic and then send the file content. It is implemented in the following method at the beginning. If the file size is small, it doesn't matter, but when the file size is large, it has a great impact on performance. [Cpp] local file = io.

Read a number of articles on the Internet, all say can be used to control the file download permissions.
The principle is that when accessing download.php, the header is verified ("X-accel-redirect: Target File").
But I have a question, if I know the real file name and storage path of the target files directly after access, it is not bypassing the x-accel-redirect?
As an example:

How the ROR website uses the X-sendfile function of Lighttpd to improve File Download Performance
In the X-sendfile mode, server applications do not need to read the downloaded files. You only need to set the response header information, in addition, you need to append the "x-Lighttpd-send-file" information to Lighttpd, telling Lighttpd that the file download will not work.

Think of a requirement like this:When using Nginx reverse proxy, we need to cache the content pulled from the back-end server, under normal circumstances, if the required content is on the back-end server, then it is easy to use NginxThe Proxy_cache module is able to implement caching. However, there is a situation where the content is not on the back-end server, but instead returns a redirect address from the back-end server, redirected to a third-party server,So this time the Nginx cache is no

The actual path of the target file has never been exposed, rather than the header redirection method used by the general Download System. In addition, there is a RENAME signal. The

Using X-sendfile will allow downloads of files in non-web directories, such as/root/, to be downloaded even if the files are not accessed under. htaccess protection.

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.
