Doesn’t my curl post request contains cookies? - php

Question

I need to login to http://auto.vsk.ru/login.aspx making a post request to it from my site.
I wrote a js ajax function that sends post request to php script on my server, that sends cross-domain request via cUrl.
post.php
<?php
function request($url,$post, $cook)
{
$ch = curl_init();
$curlConfig = array(
CURLOPT_URL => $url,
CURLOPT_POST => 1,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_COOKIEFILE => $cook,
CURLOPT_COOKIEJAR => $cook,
CURLOPT_USERAGENT => '"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 10.0; Trident/7.0; Touch; .NET4.0C; .NET4.0E; Tablet PC 2.0)"',
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_REFERER => $url,
CURLOPT_POSTFIELDS => $post,
CURLOPT_HEADER => 1,
);
curl_setopt_array($ch,$curlConfig);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$result = request($_POST['url'], $_POST['data'], $_POST['cook']);
if ($result === FALSE)
echo('error');
else
echo($result);
?>
Js code:
function postcross(path,data,cook,run)
{
requestsp('post.php','url='+path+'&data='+data+'&cook='+cook, run);
}
function requestp(path, data, run)
{
var http = new XMLHttpRequest();
http.open('POST', path, true);
http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
http.onreadystatechange = function()
{
if(http.readyState == 4 && http.status == 200)
{
run(http);
}
}
http.send(data);
}
postcross('http://auto.vsk.ru/login.aspx',encodeURIComponent('loginandpassord'),'vskcookies.txt',function(e){
document.getElementById('container').innerText=e.responseText;
});
The html page I getting from response says two things:
My browser is not Internet Explorer, I should switch to it.(actually it works from Google Chrome, at least can login).
My browser doesn’t support cookies.
About the cookies it is very similar to this (veeeery long) question. File vskcookies.txt is created in my server and it is actually updates after post request call, and stores cookies.
About the IE, firstly I thought that the site checks browser from js, but it is wrong, because js doesn’t run at all - I only read html page as a plain text, and it already has that notification about IE.
So wondered what if I make cUrl request wrong? I wrote new php script that shows request headers, here is a source:
head.php
<?php
foreach (getallheaders() as $name => $value)
{
echo "$name: $value\n";
}
?>
The result of postcross('http://mysite/head.php',encodeURIComponent('loginandpassord'),'vskcookies.txt',function(e){ document.getElementById('container').innerText=e.responseText; }):
Host: my site

For some reason there is no Cookie: parameters, but user agent is IE as I mentioned.
Also I tried to replace head.php source with
print_r($_COOKIE);
And got empty array:
Am I doing something wrong, or it is site bot-protection?
Update 1
It is showing cookies only if to pass them through CURLOPT_COOKIE.
So I think I will leave CURLOPT_COOKIEFILE => $cook; as it is, and for CURLOPT_COOKIE something like file_get_contents($cook), although there is useless information. protection?
Important Update 2
Okay, probably I just stupid. Response html page indeed consists messages about IE and offed cookies, but they are in div that is display:none and are displayed on by js.
So, seems my tries fail because of another reasons.
