How does HTTP work in practice?

The HTTP protocol is the application layer, and the socket is the transport layer. The specific implementation of HTTP is through the socket. Here's a simple example: you visit.

The socket on the server listens on his port. You, the client, the browser, create a new socket, establish a connection to the server's socket when accessing, and you send a request packet. The server socket receives the string and analyzes it, and after the analysis is completed, it returns the request packet to the resource requested by your request packet through the socket (the content is all strings).

You can search for tutorials about the language you are learning and write a server in the language you learned that can handle static pages.

With the advent of the cloud era, big data has also attracted more and more attention, the strategic significance of big data technology not only comes from the grasp of huge data information, after the analysis of these data, so that all walks of life have stronger development capabilities, and the role of web crawlers is to collect and sort out these data information.

In view of some purposes, many large ** in the network will set up anti-crawler policies, when web crawlers frequently scrape information, it is very easy to block IP, and the value of HTTP is highlighted at this moment.

With HTTP IP access, you can effectively hide your source IP address and always make the other party think that you are a new user. Before using http**ip, you should choose the right service provider according to your own needs, and a good service provider ip has full-time personnel to maintain it, and the quality and reliability are better.

A Hypertext Transfer Protocol (HYPERTEXT Transfer Protocol) is one of the most widely used network protocols on the Internet.

The main function of HTTP (HyperTextTransfer Protocol) is to transmit a wide variety of hypertext files over a network.

The Http-Hypertext Transfer Protocol defines how a browser (i.e., a World Wide Web client process) requests a World Wide Web document from a World Wide Web server, and how the server delivers the document to the browser. From a hierarchical point of view, HTTP is a transaction-oriented application layer protocol, which is an important basis for the reliable exchange of files (including text, sound, images, and other multiple files) on the World Wide Web.

Hypertext Transfer Protocol, a protocol used to transmit information over the WWW.

What exactly is the difference between HTTP and HTTPS?

1. HTTP, also known as Hypertext Transfer Protocol, is the most widely used network protocol on the Internet. All www files must comply with this standard. HTTP was originally designed to provide a kind of vertical dust for publishing and receiving HTML pages.

2. When browsing the web, the URL entered in the address bar of the browser is preceded by http: to start the residual type Zen. HTTP defines how information is formatted, how it is transmitted, and how the server and browser respond to various commands.
