handleWebSocketMessages

Description

The directive first checks if the request was a valid WebSocket handshake request and if yes, it completes the request with the passed handler. Otherwise, the request is rejected with an ExpectedWebSocketRequestRejection.

WebSocket subprotocols offered in the Sec-WebSocket-Protocol header of the request are ignored. If you want to support several protocols use the handleWebSocketMessagesForProtocol directive, instead.

For more information about the WebSocket support, see Server-Side WebSocket Support.
