cURL选项 - 会话和cookie(cURL Option - session and cookie)

 在脚本中，我使用cURL登录或将一些信息发布到另一个站点。 
 
 当用户加载此脚本时，我们没有任何问题，但是当两个用户同时加载脚本时，另一个站点加载第一页，因为我们的主机中的cookie为一个用户设置，并且该站点从用户获得两个不同的命令。 
 
 如果为该站点为每个用户获取不同的SESSION和COOKIE的任何用户加载脚本，我该怎么做？ 
 
$ch = curl_init();
$agent = $_SERVER["HTTP_USER_AGENT"];
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
$result = curl_exec($ch);
return $result;  

In a script I used cURL for login or post some information to another site.
 
When a user loads this script we have not any problem but when two user simultaneously load script the another site loads first page, because the cookie in our host set for one user, and the site get two different commands from a user.
 
How can I do that when the script was loaded for any user that the site get different SESSION and COOKIE to each user?
 
$ch = curl_init();
$agent = $_SERVER["HTTP_USER_AGENT"];
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
$result = curl_exec($ch);
return $result;
