X-accel-redirect serving html download page instead of file.

[poulphunter]

I've correct this bug adding an expire header like :

location ^~ /protected-file/ {
		expires       30s;
		add_header Pragma public;
		add_header Cache-Control "public, must-revalidate, proxy-revalidate";
		gzip off;
		internal;
		alias /;
	}

And my PHP headers are :

header("X-Accel-Redirect: /protected-file".realpath($realpath));
header("X-Accel-Buffering: yes");
header('Content-Length: '.$size);
header("Content-Type: ");
header('Content-Disposition: attachment; filename="'.$filename.'"');

Nginx MIME types are /etc/nginx/mime.conf (from normal config)
