ajax同时请求多个服务器？

这是地址， http://119.29.23.116/info.php 大侠你怎么看

想利用雅黑探针检测服务器的在线状态，但对AJAX多个请求不会操作

header('Access-Control-Allow-Origin:*');

在雅黑探针的 “//ajax调用实时刷新” 前后修改如下，

$key = '';
$value = '';
foreach($strs as $k => $v){
    if(strstr($v, 'eth0', true)){
        $value .= $v;
        $key .= $k;
        $nic = 'eth0';
    }elseif(strstr($v, 'venet0', true)){
        $value .= $v;
        $key .= $k;
        $nic = 'venet0';
    }
}
//echo $key ."\n" . $nic;
$company = 'Qcloud: ';
$ipinfo = @$_SERVER['REMOTE_ADDR'] . '(' . $_SERVER['SERVER_ADDR'] . ') - ';
if(PHP_OS == 'Linux'){
    $kernel = substr(php_uname('r'), 0, stripos(php_uname('r'), '-'));
    $os = file_get_contents('/etc/issue');
    $os = str_replace(array("\r\n", "\n", '\n', '\l'), '', $os);
    $os = trim($os) . ' - ' . $kernel;
}else{
    $os = php_uname('s') . ' ' . php_uname('r');
}
$apache =  substr($_SERVER['SERVER_SOFTWARE'], 0, stripos($_SERVER['SERVER_SOFTWARE'], ' '));
$os_info = $company . $ipinfo . $os . ' - ' . $apache . ' PHP/'. phpversion();
//echo  $os_info;

//ajax调用实时刷新

$arr=array('nic'=>"$nic", 'os_info'=>"$os_info", 'totalSpace'=>"$dt",
