X-Sendfile Error

Question

Hi,

I am trying to send files by using X-Sendfile directive in lighttpd.

My php code is;

header("Content-Type: application/force-download");
header( "Content-Disposition: attachment; filename=" . 's.php');
header("Content-Length: ". filesize("/home/web/domain/htdocs/download.php"));
header( "X-Sendfile: /home/web/domain/htdocs/download.php");

(I am sending download.php file just for testing purpose)

However, I get blank file no matter what I try. If I change the filename, I get;

2010-08-30 18:01:14: (mod_fastcgi.c.2587) send-file error: couldn't get stat_cache entry for: /home/web/domain/htdocs/downloa1d.php

So, it is working, but when I send the correct file it does not give any error in the logs and the browser downloads an empty file.

What could be wrong? What should I do?

Thanks in advance,
