Hide a download URL

Is there a way to hide the real file location?

[iProgram]

I place a file on my server at http ://www.domain.com/file/file.zip

And I want only paid users can download this file. So my question is, how to hide this file from paid user to prevent them from sharing this URL with other unpaid users.

For example, I can send header to the file's location:

Source code of http ://www.domain.com/download.php

<?
Header("Location: http ://www.domain.com/file/file.zip");
?>

But if the paid user uses some download manager (for example, FlasheGet), he will see the real file link in the log window of this download manager, like this:

2004-10-07 11:29:39.101 GET /download.php HTTP/1.1
2004-10-07 11:29:39.101 Host: www.domain.com
...
2004-10-07 11:29:39.812 HTTP/1.1 302 Found
2004-10-07 11:29:39.812 Location: http ://www.domain.com/file/file.zip
...
2004-10-07 11:29:39.812 Start Receiving Data!

So, is there a way to hide the real file location?

Btw, don't worry about that the paid users give out http ://www.domain.com/download.php because the real download.php URL is like this: http ://www.domain.com/download.php?id=the_customers_unique_id

here's a thought, rename the actual file.

1. Customer requests file.zip
2. copy the original file.zip to the_customers_unique_id.zip
3. serve them the renamed file
4. delete the file

another thought is to keep the real files outside of the root and copy them into the web root in some random folder on request.

Solved!

<?
$content_len=@filesize("file.zip");
Header("Content-type: application/zip");
Header("Content-type: octet-stream");
Header('Content-Disposition: attachment; filename="file.zip"');
if($content_len!=FALSE)
{
Header("Content-length: $content_len");
}
readfile("file.zip");
?>
