WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is being standardized by the W3C.. WebSocket is distinct from HTTP.Both protocols are located at layer 7 in the OSI model and depend on TCP at layer 4.

To establish a WebSocket connection, a specific, HTTP-based handshake is exchanged between the client and the server. The HTTP/1.1 protocol provides a special mechanism that can be used to upgrade an already established connection to a different protocol, using the Upgrade header field..

Failure to do so is the most likely cause of 403 errors when making a websocket connection. When using a secure websocket connection ( wss:// ) with a self-signed certificate, the connection from a browser may fail because it wants to show the “accept this certificate” dialog but has nowhere to show it. Mar 27, 2018 The wss:// protocol is not only encrypted, but also more reliable.. That’s because ws:// data is not encrypted, visible for any intermediary.

Apr 03, 2019 To use web-sockets when the application router is integrated with the HTML5 Application Repository, the websockets property should be added to the xs-app.json of the deployed HTML5 application. When an incoming request for an application in the repository goes through the application router, it retrieves the application's configuration from the repository. A WebSocket server is explained on a very low level here. WebSocket servers are often separate and specialized servers (for load-balancing or other practical reasons), so you will often use a reverse proxy (such as a regular HTTP server) to detect WebSocket handshakes, pre-process them, and send those clients to a real WebSocket server. This means that you don't have to bloat your server code Secure WebSocket connections improve confidentiality and also reliability because they reduce the risk of interference by bad proxies.

Some websites do not allow access through a proxy like service, such as WSS, for security reasons. Resolution Commonly, the solution to this issue is to bypass authentication and exempt the website from SSL interception.
