I'm developing an application for a client's website. Here's the story, this company uses an application/HDD called synology that is basically an HDD box connected to the internet and gives access to files to clients with pre-created accounts. This interface is written in CGI and I have no access to the box (different network and location from the website).

Uygulama giriş formu: Ne yapmak istiyorsun (D en azından kullanıcılara) atlayarak (inşa ediyorum) ana web sitesinden bir giriş formu sağlamasıdır.

Açıkçası farklı etki için bir jQuery ajax isteği yapamaz, bu iş olmaz. Peki ben yaptım olduğu

1) jQuery ile çalışan web sitesinde Formu:

$("#login_submit").click(function(){
    var username= $("input#login_username").val();
    var passwd= $("input#login_passwd").val();
    var post_string = "username=" + username + "&passwd=" + passwd ;
    $.ajax({
        type : "POST",
        url: "login.php",
        data : post_string,
        success: function(response){

            if (response){
                $('.result').html("OK");
                window.location = "http://XX.XX.net:5000/webman/index.cgi";
             }
             else {
                 $('.result').html("INVALID");
             }
        }
    })
    return false;
}

2) Call a login.php page on submit passing user and password via POST, the PHP page makes a HTTP POST request to the remote synology server and gives me a response in JSON apparently (?) that I convert to a PHP array so that I can see if the "success" key is true or false, if true the jquery code will print an OK message and redirect to the remote sylonogy server where I can access my data-logged in!

<?php
function do_post_request($url, $data, $optional_headers = null)
{
  $params = array('http' => array(
              'method' => 'POST',
              'content' => $data
            ));
  if ($optional_headers !== null) {
    $params['http']['header'] = $optional_headers;
  }
  $ctx = stream_context_create($params);
  $fp = @fopen($url, 'rb', false, $ctx);
  if (!$fp) {
    throw new Exception("Problem with $url, $php_errormsg");
  }
  $response = @stream_get_contents($fp);
  if ($response === false) {
    throw new Exception("Problem reading data from $url, $php_errormsg");
  }
  return $response;
}

if ($_SERVER['REQUEST_METHOD'] == "POST"){
    $username = $_POST["username"];
    $passwd = $_POST["passwd"];

    $response =json_decode(do_post_request($url = "http://XX.XX.net:5000/webman/login.cgi", $data = "username=".$username."&passwd=".$passwd), true);

            if($response["success"]){
                $send = true;
            }
            else {
                $send = false;
            }
        echo  $send;
}

The problem here is that the login.cgi page is supposed to set a session cookie for that server but using that PHP request it just won't. It will give a response but it won't set the cookie to the browser. Do you have any idea what I can do to imitate a POST browser request and set the cookie while maintaining that jquery function? maybe I should set some headers? If make a simple form to that login.cgi as "action" the session cookie is but the user will of course remain on that page that I can't change since I have no access to it.
