connectHeader is not passed to Spring server about stompjs HOT 1 CLOSED

I do not use Spring myself. Based on previous issues and Spring documentation I can suggest the following:

• WebSocket internally connects using HTTP(S). request.getHeader returns headers from the HTTP connection. WebSocket protocol does not allow setting custom headers for the HTTP connection.
• To get the headers from STOMP CONNECT frame you will need slightly different code. The best reference I have found is at: https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html#websocket-stomp-authentication-token-based
• This example demonstrates Token authentication, however you can authenticate using headers you are sending. Your header will be accessible through accessor which is MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class).

I hope this helps.
