Introduction to HTTP/2 Header Compression Technology (1) We know that the HTTP/2 protocol is composed of two RFC: one is RFC 7540, which describes the HTTP/2 protocol itself; the other is RFC 7541, describes the Header Compression Technology Used in HTTP/2. This article wil

Learning node (2) from 0 to 1 and building an http server During the course of the previous section, we learned about the connection and differences between different module specifications. In this section, we officially started learning about node. First, we started from setting up an http server and running simple programs.

Knowledge Point: HTTP protocol: It is based on the TCP protocol, browser access to the server, the server to the resource back to the browser, the process is to follow the HTTP protocol, otherwise cannot be completed, HTTP early is the 1.0 version, now basically is the 1.1 version, the difference between the two versions is 1.0 using a short connection, the early

Getting resources over the internet is both slow and expensive. For this reason, the HTTP protocol contains a portion of the control cache so that HTTP clients can cache and reuse previously acquired resources to optimize performance and enhance the experience. Although the part about cache control in HTTP, there are some changes as the protocol evolves. But I th

The message of HTTP is divided into request message and response message, when a Web page is opened, the browser will initiate an HTTP request message, and the HTTP server will send back a response message after receiving the request.Basic structure of the messageHTTP request and response messages are made up of three parts: the start line that describes the mess

Golang streamlined and intuitive design, allowing web development and writing print "Hello world" identical. It also gives me a chance to get a glimpse of the design and implementation of HTTP Server. So far, before Tomcat, Apache and other web containers gave me the mystique swept away.1. Basic knowledgeThe purpose of HTTP server is to implement

Under Windows, C + + uses the HTTP protocol to crawl the content of Web pages:Let's start with the next two important packages (typically open source packages under Linux, which call their dynamic-link library DLLs under Windows): Curl packets and Pthreads_dll, where the curl package is interpreted as a command-line browser by calling the built-in Curl_easy_ Setopt and other functions to achieve a specific Web content acquisition (correct compilation

proxy is "equivalent" to a TCP connection established with the server. Of course we have already said that this direct connection is just an illusion. The packet sending and receiving process is as follows: [Client]-http connect a. B. c. d: port-> [proxy]-TCP SYN-> [server][Client] [CLIENT]-ssl client hello-> [proxy]-ssl client hello-> [server] # SSL handshake Package 1[Client] [CLIENT]-ssl client certific

Recently, an android-sdk-windows.rar was downloaded from google, and the SDK manager was clicked. The API level cannot be refreshed, and a lot of information was found online. To solve this problem, the modification of hosts, HTTP, and HTTPS cannot be solved, this has brought me a lot of confusion!

about it. When the Post Office receives the mail, he sends it to the recipient Based on the address on the envelope, then, the recipient's response is taken back and sent to the sender. the HTTP Proxy acts as the post office function. Next, we first use the simplest code to implement an http proxy. To run this code correctly, we need a software Fiddler. Why do we need Fiddler, because we have only one staf

Remarks: Vary response header in HTTP network protocol (1) Those who often capture packets and view HTTP requests should be familiar with the Vary response header field. What is its purpose? When you use the PageSpeed tool to check the page, you will often see the suggestion "Specify a Vary: Accept-Encoding header (please Specify a Vary: Accept-Encoding header)"
