Re: readFile - Image Caching on client side [split]

[Vector]

Hey, i'm glad to see that someone got this working. Any chance you could take a look at mine? I echoed apache_request_headers() and $_SERVER['HTTP_IF_MODIFIED_SINCE'], but the $_SERVER version is empty each time, and the apache_request_headers does not have the if-modified-since. I send these headers on the initial download, and if you click download again, there is no caching or last-modified. I also used tamper-data to watch the headers being sent (and received), and when the server is sending the headers, it is NOT sending the cache headers.

 

 

I'm kind of desperate to get this working because i'm server VERY large image files, and mp3s, for a band who's on my servers, and fairly popular; which means that i'm about to get all of my bandwidth eaten.:

$expires = 60*60*24*365;
$size = filesize("{$client_directory}/{$_GET['did']}");
header("Content-Length: ".$size,true);
header("Cache-Control: max-age={$expires}, public, no-transform",true);
header('Expires: ' . gmdate('D, d M Y H:i:s', time()+$expires) . ' GMT',true);
header('Last-Modified: ' . gmdate('D, d M Y H:i:s', time()-$expires) . ' GMT',true);
header("Content-type: audio/example");
header("Content-Disposition: attachment; filename=\"{$_GET['did']}\"");
readfile("{$client_directory}/{$_GET['did']}");

Any help is appreciated.

So do you want me to delete this, or just go ahead and start a new topic?
