B.com/a.php?url=http://a.com/a.rar
If the file is too small to write like this

$url = isset ($_get[' url ')? $_get[' URL ']: '; if ($url) {    $content = file_get_contents ($url);    if ($content) {        header (' cache-control:public ');        Header (' Content-type:application/octet-stream ');        Header (' content-disposition:attachment; Filename= '. basename ($url));        echo $content;    }}

To ensure that
1. Celestial can visit B.Com
2.b.com can access a.com

You can use Curl

$url = ' Incoming destination URL '; $ch = Curl_init (); Initialize curl_setopt ($ch, Curlopt_url, $url),//curl_setopt ($ch, Curlopt_referer, ' one routing URL '); Forge the Antecedents page curl_setopt ($ch, Curlopt_header, 1); curl_setopt ($ch, Curlopt_writefunction, ' func '); curl_exec ($ch); Execute function func ($ch, $str) {  static $s = ' @ ';  if ($s) {    $s = trim ($str);    if ($s) header ($s);  } else echo $str;  return strlen ($STR);}

B.com/a.php?url=http://a.com/a.rar

Thank you pro, if you can join the download traffic statistics just fine

Download count?

Download count?

No. is to record the size of the file downloaded by this file plus the value.

Integrate the functionality of the download into the method and execute it once to add 1 to the data table
