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
