会话未传递给ajax（HttpOnly：Secure）

Question

My main file is:

<?php 
session_start();
$_SESSION["foo"]="foo"; 
?>
        $.ajax({
          type: "POST",
          url: "hoho2.php",
        });

And my hoho2.php is:

<?php
    session_start();
    print_r($_SESSION);
?>

Now, In my main file, where I am doing the print_r, I get the correct session data - foo -> foo. But in my hoho2.php file, I get the empty array. Why is session not passing through ajax call? Is it possible because I have Set-Cookie: HttpOnly:Secure ?

Update: I have figured out that It indeed it because of HttpOnly:Secure that my session is not persisted. What can I do ?
