}
$file = GET["file"].".".GET["type"];
if (@$fp = fopen($file,'r')){
 header ("Content-type: octet/stream");
 if (strstr(SERVER["HTTP_USER_AGENT"], "MSIE")){
 header("Content-Disposition: filename=".mb_convert_encoding('nginx中文手册.doc','GB2312','UTF-8')); // For IE
 }else{
 header("Content-Disposition: attachment; filename=".mb_convert_encoding('nginx中文手册.doc','GB2312','UTF-8')); // For Other browsers
} while(!@feof($fp)){
 echo fread($fp,1024);
