Now, let's imagine why these "checkpoints" are called "chains" in iptables. As we know, The purpose of a firewall is to match "rules" for passing messages, Then execute the corresponding Action, So, when the message passes through these checkpoints, You must match the rules on this level, However, there may be more than one rule on this level, But there are many rules, When we put these rules in a chain, A "chain" has been formed. Therefore, we imagine each "checkpoint" as shown in the following figure. In this way, it is more appropriate to call them "chain". Each message passing through this "checkpoint" must match all the rules on this "chain". If there are qualified rules, the corresponding actions of the rules will be executed.

When an attacker sends an http post request, he sets the Content-Length to a large value in the request header and sends the http body to the web server at a very slow speed, byte by byte. The web server always needs to maintain the connection with the client and wait for the data transmission to end.
