Cannot access session data - php

Question

In my project, I'm trying to access the session data from 2 files, located in 2 different directories:
/site/page.extension.php <-- initializes the session and writes data to it
- also sets a cookie with session_id() and session_name()
/extension/ajax_handler.php <-- tries to access the session data, session_id()
- and session_name() are set via cookie and return the correct values
Now, my problem is, that even though session_id() and session_name() are the same in both files, I cannot access the session-array, it just returns an empty array.
My code:
page.extension.php:
session_start();
setcookie("psc_session", session_id(), strtotime("+20 minutes"), "/");
setcookie("psc_session_name", base64_encode(session_name()), strtotime("+20 minutes"), "/");
$_SESSION['uid'] = system::current_user_id();
ajax_handler.php:
session_id($_COOKIE['psc_session']);
session_name(base64_decode($_COOKIE['psc_session_name']));
session_start();
print_r($_SESSION); // => array(0) { }
I would really appreciate any help!
Greetings!
Update:
I've tried setting the session cookie params using this in page.extension.php:
$url = str_replace("http://", '', current_url(false)); // returns the current domain
session_set_cookie_params(10800, "/", $url, 0, 1);
If I now access session_get_cookie_params I receive (in ajax_handler.php):
print_r(session_get_cookie_params()); // =>
Array
(
[lifetime] => 0
[path] => /
[domain] =>
[secure] =>
[httponly] =>
)
Why does this happen?

I cannot replicate your problem, recreating the code you supplied the session variables and the cookies remain intact and are accessible from the ajax_handler.php. I'd suggest you backtrack and make sure both files are requested from the same domain.
