Question

以下脚本在名为domain_one.com的服务器上运行。

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'https://domain_two.com/testing/curl2.php');
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,array('x'=>1,'y'=>2,'z'=>3));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);

curl2.php位于domain_two.com，并具有以下脚本：

echo('<pre>'.print_r($_POST,1).'</pre>');
echo('<pre>'.print_r($_SERVER,1).'</pre>');

当我在domain_one.com上运行第一个脚本时，我得到以下输出。

Array
(
    [x] => 1
    [y] => 2
    [z] => 3
)

Array

    [HTTPS] => on
    [SSL_TLS_SNI] => domain_two.com

    [REQUEST_TIME_FLOAT] => 1421509992.179
    [REQUEST_TIME] => 1421509992
)

domain_two.com上的脚本是否可以获取正在访问它的服务器名称（即domain_one.com）？我看到我可以获得与domain_one.com相关联的REMOTE_ADDR（即111.111.111.111）。

如果两个脚本都作为子域（即subdomain.domain_one.com）访问，会有什么影响？

我为什么这样做： domain_one向domain_two脚本发送curl请求。 domain_two设置一些标头并响应它收到请求，但不退出。相反，它会执行一些漫长的过程（一分钟左右，可能更长），当它完成时，需要向domain_one发送一个curl请求，指示它已完成。
