Here is a script I use to send pdfs which also handles caching
information. It may just be you are missing the content-length header?
<?php
$cache_time = false;
$requested_time = false;
$filename = "/tmp/" . session_id() . ".pdf";
$len = filesize($filename);
$mtime = filemtime($filename);
$cache_time = gmdate('D, d M Y H:i:s', $mtime) . ' GMT';
header('Last-Modified: '.$cache_time);
$rt = (empty($_SERVER['HTTP_IF_MODIFIED_SINCE']))? false : $_SERVER['HTTP_IF_MODIFIED_SINCE'];
if($rt) $requested_time = strtotime($rt);
if($requested_time && $cache_time){
if($requested_time == $cache_time){
Header($_SERVER['SERVER_PROTOCOL'].' 304 Not Modified');
exit;
}
}
header("Accept-Ranges: bytes");
header('Cache-Control: no-cache, must-revalidate');
header("Content-type: application/pdf");
header("Content-Length: $len");
readfile($filename);
