What are the advantages and disadvantages of using URL sessions as a solution for preventing repeated voting in PHP?

Issue: Preventing repeated voting in PHP can be achieved by using URL sessions to track and restrict multiple votes from the same user. Advantages of using URL sessions: 1. Easy to implement and maintain. 2. Provides a simple way to track user activity and prevent multiple votes. 3. Can be used to set time limits for voting to prevent spamming. Disadvantages of using URL sessions: 1. Users can potentially clear their browser cookies and vote multiple times. 2. Requires additional server resources to manage session data. 3. May not be as secure as other methods of preventing repeated voting. PHP code snippet: 

<?php
session_start();

if(isset($_SESSION['voted'])) {
    echo "You have already voted.";
} else {
    // Process the vote
    $_SESSION['voted'] = true;
    echo "Thank you for voting!";
}
?>
