DNS spoofing technology principle and Security Protection Technology Overview: What is DNS spoofing?DNS Spoofing is the art of changing the original IP address of DNS. For better understanding, let's look at an example. If you want to use your browser to search for some information on Google, you can enter www.google.com in the address bar and press Enter.So what is going on behind this? Generally, your br

application server will not become the bottleneck of the website system.The second phase of your hardware is so expensive, let's get some technology.1. On-Cache Most users of the business access to a small number of data, spicy we can put this small amount of data in memory, you have to use it from memory, the database pressure is much smaller, the system response speed is fast.The cache is also divided into local cache and remote distributed cache,

technique for creating fast, Dynamic Web pages.　　The ability to update parts of a Web page without reloading the entire page. Ajax enables Web pages to be updated asynchronously by exchanging small amounts of data in the background with the server. This means that you can update a part of a webpage without reloading the entire page. Traditional Web pages (without Ajax) if you need to update the content, you must reload the entire page page. 2.2 Effects:2.2.1 Ajax uses asynchronous data transfer

Forward forecast: 21st century will produce eight future technology series A What happens if eight different technologies are present at the same time. In this respect, Peter Diamandis on February 8, 2016 to discuss his views. Here, I will share a series of blogs with my readers, and in the blog Peter will describe the following areas that will change and be combined to create an unexpected future. So what do these areas include? Calculation Internet

This kind of pressure is very small, not learn and art this bowl of rice. reason two: just amateur study, this study is just a play, because you do not have to use this technology to eat. reason three: the method is wrong, some people just look at the tutorial, but he does not do, I used to see too much, do too little, so have the practice you can put the t

Today, wireless service providers have been seeking cheaper voice services to maintain their market share. Obviously, the secret to surpassing competitors is to launch some attractive services with additional charges. However, existing technologies such as SMS need the same cost model as voice. Therefore, wireless service providers focus on the commercial technology of Session Initiation Protocol (SIP. SIP is an application standard in the 3G era, but

This article describes in detail the basic configuration of the route redistribution technology, as well as the application of OSPF and RIP technology. The following article gives a detailed introduction. In practice, we will encounter a network that uses multiple IP routing protocols. To make the entire network work normally, routes must be successfully distributed among multiple routing protocols. The fol

UWP hand-drawn video creation tool technology sharing series, uwp tool technology We have introduced the analysis and drawing of SVG. SVG is a form of image, and another very important image is: bitmap, formats include png, jpeg, and bmp. The basic rule of bitmap is that the basic element is a pixel, which consists of * width * Height pixels. Each pixel stores the color and position information of a vertex,

The main ideas of von loiman: (1) use binary code to represent programs and data; (2) computers use storage programs; (3) computer hardware consists of five components: memory, memory, controller, input device, and output device. 2.

Both of these methods can be implemented correctly and quickly, but as two communication, but there are obvious differences, the first method of communication is particularly fast end, this I can see through the output of the server, but the second communication to wait for several minutes to end, I tried several times this, I'm not sure where my program went wrong, or the way the connection is problematic, but the second way to do this two communi
