Zahtevi su bili:
1) Ogranicenje brzine downloada
2) Rad sa akceleratorima, resume support
download.php, ovde se salju headeri, i poziva funkcija za download
EDIT: Ok, akcelerator radi, al nece resume, tj krene on, predje par kilobajta (5 npr) i stane, kao gotovo..
$mimes = mimeTypes('/home/share/public_html/mimes');
$ext = explode(".",$file);
foreach($ext as $val){
$ekstenzija = $val;
}
$ext = strtolower($ekstenzija);
// use them ($ext is the extension of your file)
if (isset($mimes[$ext])) {
$type = $mimes[$ext];
}
else {
$type = 'application/force-download';
}
$size = filesize("uploads/$id"."-".$file);
$seek_start = 0; // Default values. Will override them latter if the download is partial (resume)
$seek_end = $size;
ini_set("zlib.output_compression", "Off"); // Some browsers (Opera) corrupt the file if this is on
header("Cache-Control: ");// leave blank to avoid IE errors
header("Pragma: ");// leave blank to avoid IE errors
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // neki dan u proslosti
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Content-Transfer-Encoding: binary");
header("Content-Type: $type");
header("Content-Disposition: attachment; filename=\"$file\"");
// check if http_range is sent by browser (or download manager) . This is used for resuming downloads
if (isset($_SERVER['HTTP_RANGE'])) {
$seek_range = substr($_SERVER['HTTP_RANGE'] , strlen('bytes='));
$range = explode('-',$seek_range);
if ($range[0] > 0) {
$seek_start = intval($range[0]);
}
else {
$seek_start = 0;
}
if ($range[1] > 0) {
$seek_end = intval($range[1]);
}
else {
$seek_end = $size-1;
}
header("Content-Length: " . ($seek_end - $seek_start + 1));
header('Accept-Ranges: bytes');
header("HTTP/1.0 206 Partial Content");
header("status: 206 Partial Content");
header("Content-Range: bytes $seek_start-$seek_end/$size");
}
else {
header("Content-Length: $size");
}
E sad sta je fora, ovaj kod gore ne radi nikako, ako izbacim Content-Length header radi bez resume-a.
Al onda nemam velicinu fajla ispisanu, a ne prihvata ni jedan Length (Ukupan, sabran itd...)
Imam osecaj da je on i kriv sto resume ne radi (posto dobro krene, al prerano stane)
Tako da ja tipujem na headere...
Funkciju sam izbacio posto ona sigurno nije uzrok...
P.S. Ako se pitate zasto su komentari englesko-srpski, to je zato sto nije sav kod moj... Ja komentarisem na engleskom (navika od rada sa strancima),a prethodni programer na srpskom...
