        <?php
        // Start the session for caching
        session_start();

        // Set cache duration (in seconds)
        $cache_duration = 3600;

        // Generate a cache key based on the current page
        $cache_key = 'page_cache_' . md5($_SERVER['REQUEST_URI']);

        // Check if the cache exists and is not expired
        if (isset($_SESSION[$cache_key]) && (time() - $_SESSION[$cache_key]['time'] < $cache_duration)) {
            // Use cache
            echo $_SESSION[$cache_key]['content'];
        } else {
            // Generate content because cache is not available or expired
            ob_start();

            // Simulate content generation (e.g., database queries)
            echo "<h2>Welcome to My Blog</h2>";
            echo "<p>This is an example of cached content.</p>";

            // Store the generated content in the session
            $_SESSION[$cache_key] = [
                'time' => time(),
                'content' => ob_get_contents()
            ];

            ob_end_flush(); // Send output to the browser
        }
        ?>
