speed of the database is too high, which will slow down and affect the efficiency. Second, some ip addresses may only be proxies for the moment, such as bots, which may return to normal, for example, if the ip address dynamically assigned by the carrier is used as an agent today, it may not be a proxy if it is assigned to you tomorrow. If there is no good detection and removal mechanism, it is very likely

Crude CC attack-HTTP Flood
HTTP Flood is an attack on Web Services in Layer 7 protocol.Hazard:
Simple attack methods, difficult defense and filtering, and huge impact on hostsAttack method:
HTTP Flood attacks do not need to control a large number of bots. Instead, they use port scanning programs to search for anonymous HTTP proxies or SOCKS proxies on the Interne
application of HTTP is far more than just browsing Web content. Because HTTP is both simple and pervasive, many other Web applications have chosen it, especially with the use of soap and XML-RPC.Explains the HTTP protocol in detail, including how it works, and how it can be used to develop web-based applications. But this book does not only introduce HTTP, but also explores all the other core Internet technologies that HTTP works on. Although HTTP is the center of the book, the Essence of the b

, DDoS attacks will cause network resource wasting, link bandwidth congestion, server resource exhaustion and business interruption. Most of these attacks are carried out by computers that are illegally controlled by hackers. After hackers illegally control some computers, they turn these computers into "bots" that are remotely controlled by underground networks, and then use these com
AIML, full name is artificial Intelligence Markup Language (AI Markup Language), is an XML language for creating natural language software proxies, which is made by Richard Wallace and the free software community around the world were invented from 1995 to 2002, and through this article we introduce how Python uses AIML to build chat bots, and friends need to learn together.

502 Bad Gateway
Servers (which can be not Web servers) are gateways or proxies that meet customer requirements (such as Web browsers or our Checkupdown bots) to access the requested URL. This server received an invalid response from an upstream server to fulfill its requirements. Meaning: This usually does not mean that the upstream server has been shut down (no response gateway/proxy)

Although FrontPage itself offers many components that allow you to add special effects to a Web page without having to know the JavaScript language, FrontPage itself builds only a handful of components and dynamic effects that are far from satisfying everyone's needs.

When your computer is controlled by others, it is like the meat on the chopping board of others. what others want to eat is what they want, and a zombie (MACHINE) comes from it.Generally, computers that are exploited by attackers and can be remotely controlled by Trojans, system vulnerabilities, and backdoors are "bots ".(2) What is "com
