WebSocket
Function Introduction
EdgeOne supports WebSocket protocol access, which enables the server to actively push data to the client. WebSocket protocol is a persistent protocol based on TCP, which implements full-duplex communication between the client and the server, allowing the server to actively send information to the client. Before the WebSocket protocol, Web Apps that implemented client-server duplex communication had to constantly send HTTP requests for inquiries, which led to increased service costs and inefficiency. Due to the advantages of full-duplex communication, WebSocket is widely used in social subscription, collaborative office, market updates, interactive live streaming, online education, Internet of Things, and other scenarios, which can better save server resources and bandwidth, and achieve more real-time communication.
Note:
1. Currently, only HTTP/1.1-based WebSocket is supported, and HTTP/2 WebSocket is not supported.
2. Maximum connection timeout duration supported: 300 seconds.
