<?php
header("HTTP/1.0 404 Not Found");
?>
PHP scripts often generate dynamic content that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with:
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>
If you want the user to be prompted to save the data you are sending, such as a generated PDF file, you can use the Content-Disposition header to supply a recommended filename and force the browser to display the save dialog.
<?php
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="document.pdf"');
readfile('document.pdf');
?>
To send authentication dialog to user use this code:
<?php
header("WWW-Authenticate: NTLM");
?>
