wikipedia:WebSocket (2011) is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol defines a ws://
and wss://
prefix to indicate a WebSocket and a WebSocket Secure connection, respectively.
The URL to which to connect; this should be the URL to which the WebSocket server will respond. This should use the URL scheme wss://, although some software may allow you to use the insecure ws:// for local connections.
Web Server implementation[edit]
- Amazon ELB support WebSockets and HTTP/2 since 2016 [1]
- Nginx supports WebSockets since 2013, implemented in version 1.3.13 [2] including acting as a reverse proxy and load balancer of WebSocket applications.[3]
