Use Ethereal or your own tracer to find out! And compare to a direct request to a real file! AFAIK the headers sent here are: 'Content-Type' => 'application/x-octetstream', (perhaps other) 'Cache-Control' => 'public', 'Accept-Ranges' => 'bytes', 'Connection' => 'close' >> And the first comment of: >> >> http://www.php.net/manual/en/function.session-cache-limiter.php > Thanks, I've read that and I'm not using output compression. Did you try something like this: <?php header("Content-Type: application/pdf"); header("Content-Disposition: inline; filename=foo.pdf"); header("Accept-Ranges: bytes"); header("Content-Length: $len"); header("Expires: 0"); header("Cache-Control: private"); // header("Pragma: no-cache");//don't send this header!! ?> What headers are sent at this moment?

How should your client recognize any difference? There _must_ be a difference! Use a very small file to test it, so you can compare the whole HTTP-Header + Body easily. >> you can see this using Mozilla + Live Headers, Ethereal, >> http://schroepl.net/cgi-bin/http_trace.pl ... > > Thanks, I've written my own HTTP header tracer in C++, but it hasn't > been able to help me since the headers looks good to me... Oh, I could not know ;-) Kind Regards, Andreas
