HTTP-REFERER這個變量已經(jīng)越來越不可靠了，完全就是可以偽造出來的東東。

以下是偽造方法：

ASP:

復(fù)制代碼代碼如下:

dim http
set http=server.createobject("MSXML2.XMLHTTP") '//MSXML2.serverXMLHTTP也可以
Http.open "GET",url,false
Http.setRequestHeader "Referer","http://www.dc9.cn/"
Http.send()

PHP(前提是裝了curl):

復(fù)制代碼代碼如下:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, "http://www.dc9.cn/xxx.asp");
curl_setopt ($ch, CURLOPT_REFERER, "http://www.dc9.cn/");
curl_exec ($ch);
curl_close ($ch);

PHP(不裝curl用sock)

復(fù)制代碼代碼如下:

$server = 'www.dc9.cn';
$host    = 'www.dc9.cn';
$target  = '/xxx.asp';
$referer = 'http://www.dc9.cn/';    // Referer
$port    = 80;
$fp = fsockopen($server, $port, $errno, $errstr, 30);
if (!$fp)
{
   echo "$errstr ($errno)<br />/n";
}
else
{
        $out = "GET $target HTTP/1.1/r/n";
        $out .= "Host: $host/r/n";
        $out .= "Cookie: ASPSESSIONIDSQTBQSDA=DFCAPKLBBFICDAFMHNKIGKEG/r/n";
        $out .= "Referer: $referer/r/n";
        $out .= "Connection: Close/r/n/r/n";
        fwrite($fp, $out);
        while (!feof($fp))
        {
                echo fgets($fp, 128);
        }
        fclose($fp);
}

VB.NET/C#.NET

復(fù)制代碼代碼如下:

Dim oXMLHttp As MSXML2.XMLHTTP30 = New MSXML2.XMLHTTP30()
或者
MSXML2.XMLHTTP30 oXMLHttp = new MSXML2.XMLHTTP30();
oXMLHttp.open(....
oXMLHttp.setRequestHeader(...
oXMLHttp.send(..

javascript

xmlHttp.setRequestHeader("Referer", "http://URL");//???呵呵~假的~
