Are there any potential pitfalls when using jQuery-Ajax calls with PHP sessions?

When using jQuery-Ajax calls with PHP sessions, one potential pitfall is that the session may not be properly maintained between requests, leading to unexpected behavior or session data loss. To solve this issue, you can pass the session ID in each Ajax request and reinitialize the session using session_id() function before accessing session data. 

<?php
session_start();

if(isset($_POST['session_id'])) {
    session_id($_POST['session_id']);
    session_start();
}

// Your Ajax request handling code here
