How to implement the display of your files for each user of the site from the same directory?

Question

PHP

It is necessary that an authorized user sees his files at http://domain.com/files/myfile.pdf, but the file is actually stored in a folder, for example, /allfiles/user1/myfile.pdf. At the same time, everyone needs that when displaying images in this way, they load quickly, just like from a real directory, and get into the browser cache.
I tried this:
header('Content-type: image/png');
readfile($_SERVER['DOCUMENT_ROOT'].'/allfiles/user1/image.png');
But such an implementation significantly slows down the output of images.

Answer 1

use nginx and X-Accel-Redirect

Answer 2

Return a 301 redirect and the actual url of the file.

<?php
  header(“HTTP/1.1 301 Moved Permanently”);
  header(“Location: {$_SERVER['DOCUMENT_ROOT']}/allfiles/user1/image.png”);
?>
