This chapter describes how to use the WebSocket API to control protocols and create applications, and using the existing WebSocket servers provided by http://websocket.org, we can send and receive messages, and create some simple websocket applications. Step-by-step learning to use the

Websocket.org compared the performance benefits of polling and Websocket:As can be seen, the WebSocket has a great performance advantage, the flow and load increase in the case of more obvious advantages.ExampleBrowser requestGET / HTTP/1.1Upgrade: websocketConnection: UpgradeHost: example.comOrigin: nullSec-WebSocket-Key: sN9cRrP

The general man-in-the-middle attack is basically to intercept and modify the contents of the normal HTTP protocol, and there seems to be little introduction to how to intercept and modify the contents of the WebSocket protocol.Talk is cheap show me the CodeUsing system;using system.collections.generic;using system.componentmodel;using system.data;using System.Drawing; Using system.linq;using system.text;using system.threading.tasks;using system.windo

Function: Use websocket technology to display the log information on remote server in real time on the browser of operation and Maintenance toolIn general, we need to present the information in the deployment process in real time when the OPS tool is deployed, or show the program log to the developer in real time in the browser.
