What Is a Slow HTTP Attack?
Slow HTTP attacks are a variation of CC attacks. Here is how slow HTTP attacks work:
The attacker establishes a connection to the target server which allows HTTP access. Then the attacker specifies a large content length and sends packets in an extremely low rate, such as one byte per one to ten seconds. The connection is maintained this way. If the attacker keeps establishing such connections, available connections on the target server are slowly consumed and the server will stop responding to valid requests.
