including results remote php script

I want to use the include function in order to get only the results of the php script on the remote server.

So I have the following script (file.php) running on server www.serverA.com

<?php

$number = $_COOKIE["kaart"];

I have the script

<?
include 'http://www.serverA.com/file.php';
if ($number) {
echo $number;} else {
echo "test2";
}

Now i do not get a value for $number in the second script

What do i do wrong?

I think,

The cookie "kaart" is created by Server A, not B.

Even if both servers have cookies named "kaart", it will be
a seperate cookie because the servers' sessions are different.

Both NAME of a cookie and SESSION identifies the specific cookie.
