The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

Explain the template method mode, which means: in an abstract class, there is a main method, and then define 1... n methods, which can be abstract or actual methods, define a class, inherit the abstract class, override the abstract method, and realize the call to subclasses by calling the abstract class. First look at a diagram:

Conclusion: The page with SingleInstance is initially created with a task stack to this page, and then the pages in this stack are reused all the time. Note that only this mode will create a new stack for the initialized page. The rule of return is to finish the stack where this page is located first, and then finish each page of the next stack.

当然了，在不久的将来，或许该称呼他为胶东相国更合适。

Slow POST attack uses POST request method. The attacker sends POST request message to the target server to submit data. The length of the data is set to a large value. However, in the subsequent data transmission, only a small message is sent each time, which causes the target server to wait for the attacker to send data. If an attacker controls a large number of zombie hosts to launch such attacks on the target server, the server will run out of resources and cannot provide services normally.
