What Is a Slow HTTP Attack?

Slow HTTP attacks are a variation of CC attacks. Here is how slow HTTP attacks work:

An attacker establishes a connection with a large content length from the client to the server, then sends packets to the server at a slow rate (e.g., one byte every one to ten seconds), maintaining the connection.

If the attacker continues to create such connections, the server's available connections are gradually consumed, causing the server to reject normal user requests.
