This mechanism is optional; it cannot be used to insist on a protocol change. Implementations can choose not to take advantage of an upgrade even if they support the new protocol, and in practice, this mechanism is used About HTML5 WebSocket The HTML5 WebSockets specification defines an API that enables web pages to use the WebSockets protocol for two-way communication with a remote host.

Then, it performs the SHA-1 hash of the result, which will finally be encoded in base64 before being See full list on infoq.com See full list on developer.mozilla.org In exactly the same way, WebSocket Secure (WSS) first establishes a secure envelope, then begins the HTTP handshake, and then the upgrade to the WebSocket wire protocol. In other words, just like HTTPS is not really a different protocol but is HTTP transported over TLS, WSS is not a different protocol but is WS (WebSocket) transported over TLS. I am directly making connection using url 'wss://test.example.com:8090/'.

Both client and server negotiate the connection details. Either of the parties can back out if the terms are unfavourable. The connection handshake carries the name of a Hybrid Connection configured on the Relay namespace, and a security token that confers the "Listen" right on that name.

Follow Oct 10, 2020 Therefore, if your secure WebSocket connection dies before ending the handshake, it could mean that the certificate has not been accepted.
