3. Some classes, such as the core trading engine of the exchange, control the trading process. If multiple classes can be created, the system will be completely messed up.

The general code is like this, and I feel that the code using the intermediary mode is similar, so I won't introduce it much here. The code in the book has advantages, but I don't feel that there is much difference, so I no longer use the intermediary mode to write code here. State mode is an unusually excellent mode, which may be the best way to solve some requirement scenarios. Although the state mode is not a simple to clear mode (it often brings about an increase in the amount of code), once you understand the essence of the state mode, you will certainly thank it for its incomparable benefits in the future. The key to the state mode is to distinguish the internal state of things. Changes in the internal state of things often bring about changes in the behavior of things. This article describes the state mode in detail
When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.
