Sao chép mã

Kết quả: tất cả ip không nằm trong list được phép ( allow ) trong file .htaccess thì sẽ không truy cập được vào site bạn cũng như các tool ddos không thể kết nối đến site bạn. Dĩ nhiên là không có gì tuyệt đối nhé. Chứ BOTNET nó chỉ cần 1 lần connect server bạn phải - Deny 1 lần thế đủ xỉu.

Chúc sống sót ^^
