Anti CC Setting

CC Protection is a specialized defense mechanism designed to safeguard websites against Challenge Collapsar (CC) attacks, a type of DDoS attack where malicious traffic mimics legitimate requests to overload server resources. By identifying and filtering out these harmful requests, CC Protection ensures that your website remains accessible and performs optimally under attack.
