First, the theme : Real-time display server-side dynamically generated log files
Second, the process :
1. The client browser establishes a WebSocket link with the server, the server suspends the Save link instance, waits for the new content to trigger the return action
2. Log server scripts loop to discover new content and discover new lines to tornado waiting for API POST to send new content
3. The Tornado processor receives new content and returns a

The WebSocket protocol defines two URL schemes, where WS and WSS represent unencrypted and encrypted communication between the client and the server. WS (WebSocket) is similar to HTTP URLs, while the WSS (WebSocket security) URL indicates that connections are based on the Secure Transpo

In the NodeJS script, you can use simple JavaScript to create a regular message sender:CODE:// Create a sender that regularly sends messages to the client every 5 seconds.Var interval = setInterval (function (){Clien
Introduction and principle of websocket
WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex). The first handshake needs to be done with an HTTP request.
