可能用Apache对下载目录作了限定，只由3个ip可以下，老大快帮帮小弟想想向Apache假冒IP的办法呀！！！

//骗程序的：
$header="GET $url HTTP/1.1\nAccept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, */*\nReferer: $referer\nAccept-Language: zh-cn\nUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MyIE2; .NET CLR 1.1.4322)\nREMOTE_ADDR: xxx.xx.xx.xxx\nHTTP_X_COMING_FROM: xxx.xx.xx.xxx\nHTTP_COMING_FROM: xxx.xx.xx.xxx\nHTTP_X_FORWARDED_FOR: xxx.xx.xx.xxx\nHTTP_FORWARDED: xxx.xx.xx.xxx\nHTTP_VIA: xxx.xx.xx.xxx\nHost: $host\n\n";
// exit;
header("Content-type: application/x-gzip");
header("Content-Disposition: attachment; filename=$name");
header("Content-Description: PHP5 Generated Data");
$referer=$url;
$fp = fsockopen($host,$port, &$errno, &$errstr, 10);
if(!$fp)
{
echo "你请求的网址$header 有错误，文件已删除，请更换其它路径！";
}
else
{
fputs($fp,$header);
while(!feof($fp))
{
echo fgets($fp,128);
}
fclose($fp);
}
