What are the potential security risks of using anonweb with a proxy instead of a web server in PHP?

Using anonweb with a proxy instead of a web server in PHP can pose security risks such as exposing sensitive data, enabling malicious activities, and bypassing security measures. To mitigate these risks, it is important to implement proper authentication, input validation, and secure communication protocols.

// Example of implementing authentication in PHP
session_start();

if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    header('Location: login.php');
    exit();
}
