In a Slow Post DDoS attack, the attacker sends legitimate HTTP POST headers to a Web server. In these headers, the sizes of the message body that will follow are correctly specified. However, the message body is sent at a painfully low speed. These speeds may be as slow as one byte every two minutes. Since the message is handled normally, the targeted server will do its best to follow specified rules. As in a Slowloris attack, the server will subsequently slow to a crawl.
