alguien que sepa sobre ataques ddos o xss, etc. Ya se que para que no te hagan ningun ataque es programarlo todo perfecto pero de hay a llegar a proteger ataques ddos a mi hosting profesional va un trecho si me hace un poco raro todo este codigo hay cosas que entiendo pero otras no le veo la pizca de sentido como hacer mi propio .htaccess, quiero sobre todo sobre ATAQUES DDOS si teneis los conocimientos suficientes tengo algo como esto:
.htaccess
