Help me in starting multiple streams of a file

I am trying to stream a file to a user from rapidshare but, when i do it only one stream opens up or lets say, i only know how to open one stream.
So when the file starts downloading it is not supported by download managers and has no resume functionality
here is the code :

if (!isset($_POST['_user'])){
header("location: index.html");
/* TODO */
}else{
$url = $_POST['_user'];
if (preg_match('/^http:\/\/rapidshare.com\/files/',$url)){
	$cookie=$accounts[min_key($leftmb)];
	$url_parsed = parse_url($url);
	$host = $url_parsed['host'];
	$path = $url_parsed['path'];

	$out = "GET $path HTTP/1.0\r\nHost: $host\r\nCookie: user=$cookie\r\n\r\n";
	$fp = fsockopen($host, 80, $errno, $errstr, 30) or die("<script>alert('File not Found.')</script>");
	fwrite($fp, $out);

	while (!feof($fp)) {
		$page .= fgets($fp, 128);
	}
	fclose($fp);

	preg_match ('/Location: ([^ ]*)\r\n/',$page, $matches);
	$url = $matches[1];
	$url_parsed = parse_url($url);

	$host = $url_parsed['host'];
	$path = $url_parsed['path'];

	if ($url_parsed['query'] != '') $path .= "?".$url_parsed['query'];
	$out = "GET $path HTTP/1.1\r\nHost: $host\r\nCookie: user=$cookie\r\n\r\n";
	$fp = @fsockopen($host, 80, $errno, $errstr, 30) or die("<script>alert('File not found.')</script>");
	fwrite($fp, $out);

$ok = 0;
while (!feof($fp)) {
$line = fgets($fp, 8192);
if ($ok==1){
echo $line;
}else{
if (preg_match('/(HTTP\/1)|(Date:)|(Connection:)|(Content-Type:)|(Accept-Ranges:)|(Content-Disposition:)|(Content-Length:)/', $line)){
If (preg_match('/Content-Type: text\/html/', $line)){
die ("<script>alert('Over Bandwidth. We are sorry :(')</script>");
}
header ("$line\r\n");
}
if ($line=="\r\n") $ok=1;
}
}

fclose($fp);
//
}
}

?>
