, there is also a http-ng is still in the experiment, this first regardless. In the following blog I will combine the Telnet window to illustrate the differences between the 2.In the HTTP1.0 version, the browser requests a Web page with a picture, which opens a new connection to the server due to the download of the image, for example, I'm going to load an HTML page that imports a lot of CSS files or pictures, It's going to keep going. Connect to the server to get these resources this is very pe

The transmission of the postman and the Post Office (network protocol overview) signals must always comply with certain protocols ). For example, the Great Wall is filled with Wolf smoke because the physical signal of the wolf smoke has been preset to represent the abstract signal of "enemy intrusion. Such a "Wolf smoke = enemy intrusion" is a simple protocol. Th

When we explain the TCP protocol, we should note that the TCP protocol is a protocol set. One of the Protocols is UDP. This is the user data packet protocol we will introduce to you today. So what is it for? What is its structure? Here we will go one by one. UDP protocol Use

of these fields are delimited by whitespace . (2), first A. Common headerEach HTTP header has a simple syntax: The name is followed by a colon (:), followed by an optional null, followed by the field value, and finally a CRLF.The HTTP specification defines several header fields. The application is also free to invent its own header.Common Header InstancesB. The first continuation lineDividing a long header line into multiple lines can improve readability by having at least one space before each

and easy to implement, but the disadvantage is that the reliability is poor, once the packet is sent, it is impossible to know whether the other party received.In order to solve this problem and improve the network reliability, the TCP protocol was born.This protocol is more complex, you can simply understand that on the basis of UDP added some to ensure that the data can be transferred to the mechanism, o

USB transfer mode, applied in the case of physical devices connected to the host side of the ADB server by using the USB protocol Local transfer mode, where the emulator running on the host is connected through the TCP protocol and the ADB server In theory, it is feasible to write a local transfer mode to implement the ADB server and the connection agent for the Android device/emulator t
