What alternative solutions, apart from PHP, could be used to restrict traffic in a download area?

The issue of restricting traffic in a download area can also be solved using server-side technologies such as Python, Node.js, or Ruby on Rails. These languages provide similar functionalities to PHP and can be used to implement access control mechanisms for downloading files. ```python # Python code snippet to restrict traffic in a download area from flask import Flask, send_file, request app = Flask(__name__) @app.route('/download/<filename>') def download_file(filename): # Implement access control logic here if request.remote_addr == '127.0.0.1': return send_file(filename) else: return "Access denied" if __name__ == '__main__': app.run() ```
