New Comment:
can you kindly rephrase your question. i am not too sure i understand
your question here.
If I understand you correctly, you want to find out a way so that
client (like browser) can request this page with 'If-Modified-Since' in
its header so that the server doesn't have to send it again.
if this is your question, then this is a server configuration issue and
nothing to do with a php engine.

Description:
------------
If this section is in your httpd.conf:
<FilesMatch "\.(php)$">
Header unset Cache-Control
Header unset Expires
Header unset Last-Modified
FileETag None
Header unset Pragma
</FilesMatch>
Then the cache headers here will not be used:
$expires = 60*60*24*365;
$size = filesize("{$client_directory}/{$_GET['did']}");
$last = filemtime("{$client_directory}/{$_GET['did']}");
header("Content-Length: ".$size,true);
header("Etag: ".md5($last),true);
header("Server: Ionisis.com",false);
header("Cache-Control: max-age={$expires}, public,no-transform",true);
header('Expires: ' . gmdate('D, d M Y H:i:s',($last+$expires)) . '
GMT',true);
header('Last-Modified: ' . gmdate('D, d M Y H:i:s', $last) . '
GMT',true);
header("Content-type: audio/example");
header("Content-Disposition: attachment;
filename=\"{$_GET['did']}\"");
readfile("{$client_directory}/{$_GET['did']}");
and even if you remove that section, and these headers are sent, the
client is still not sending a "if-modified-since" header that can be
captured at the server level for the php level.
Firefox 3.5, Apache 2.2, PHP 5.3, Fedora Linux
Reproduce code:
---------------
Just copy that code, and paste it in an file called download.php, and
set it up so that it grabs an mp3 file, then beat your head into the
desk for 2 days :D
Expected result:
----------------
I expected it to send the proper cache headers, despite what the server
was preconfigured to send.
Actual result:
--------------
Had to remove the server's configuration section pertaining to caching
php output.
