Can I add cookie with Spring SockJs websocket implementation

Can I add custom cookies over websocket in Spring SockJS implementation?
The way we can add it with http request/ response?
Forget to mention that I see way to read cookie from headers ::
HttpHeaders headers= session.getHandshakeHeaders(); -But I do not see a
way to set headers. With headers I can read the cookies -but how to set
it?
