UpgradeToWebSocket

trait UpgradeToWebSocket extends scaladsl.model.HttpHeader with WebSocketUpgrade

A virtual header that WebSocket requests will contain. Use UpgradeToWebSocket.handleMessagesWith to create a WebSocket handshake response and handle the WebSocket message stream with the given handler.

This low-level API is expected to be replaced by an Attribute in the future.

In any case, you might want to use handleWebSocketMessages instead as documented at https://doc.akka.io/docs/akka-http/current/server-side/websocket-support.html#routing-support

(Since version 10.2.0) use the WebSocketUpgrade attribute instead
