WebSocket and HTTP protoco

BackgroundPreviously, many websites used polling to implement push technology. Polling is at a specific time interval (for example, 1 seconds), the browser sends an HTTP request to the server, and the server returns the latest data to the browser. The disadvantage of polling is obvious, the browser needs to constantly make requests to the server, however, the header of the HTTP request is very long, and the actual transmission of data may be very small, resulting in a waste of bandwidth and serv

WebSocket SecurityThe WebSocket protocol is a young technology, and brings with it some risks. Decades of experience has taught the web community some best practices around HTTP security, but the security best practi Ces in the WebSocket world aren ' t firmly established, and continue to evolve. Nevertheless, some themes has emerged and they is described in this

client and server side of the WebSocket connection is established, after the connection is established, and HTTP is not related, the two sides can pass through this connection channel free information.Of course, it is possible that the server does not support WebSocket, then honestly use HTTP bar, most of the current browser and server has supported WebSocket.Paste a s
