Using X-Sendfile with Apache/PHP

apache, php, x-sendfile

Solution

X-Sendfile is an HTTP header, so you want something like this:

header("X-Sendfile: $filename");

Your web server picks it up if correctly configured. Here's some more details:

Problem

I can't seem to find much documentation on X-Sendfile or example code for PHP (there is some rails code). Anyone used it before and would mind giving a quick snippet of code and a brief description?
