Forged Referer

Forged Referer

Request Code

$url = '/A connection address url.rar format '; $ch = Curl_init (); Initialize curl_setopt ($ch, Curlopt_url, $url); The page you want to visit curl_setopt ($ch, Curlopt_referer, ' One of the antecedents URL '); Forge the Antecedents page curl_setopt ($ch, Curlopt_header, 1); To read back the HTTP header curl_setopt ($ch, Curlopt_writefunction, ' func '); Monitor the returned data curl_exec ($ch); Execute function func ($ch, $str) {  static $s = ' @ ';  if ($s) {    $s = trim ($str);    if ($s) header ($s); If it is the header information, send the corresponding head  }else echo $str; Otherwise send data  return strlen ($STR);}

Since the other side provides the download, then the relevant information has been provided, including the file name and length
