One thing that worked for me was to reimplement the ***HttpSessionStrategy using code from both Cookie and Header implementations.

You can see the concrete implementation of these classes here:

So the getRequestedSessionId becomes:

public String getRequestedSessionId(HttpServletRequest request) {
        // header part
        String sessionId = request.getHeader(headerName);
        if(sessionId != null && !sessionId.isEmpty())
            return sessionId;

        // cookie part
        Map<String,String> sessionIds = getSessionIds(request);
        String sessionAlias = getCurrentSessionAlias(request);
        return sessionIds.get(sessionAlias);
    }

onInvalidateSession becomes:

public void onInvalidateSession(HttpServletRequest request, HttpServletResponse response) {
    // header part
    response.setHeader(headerName, "");

    // cookie part
    Map<String,String> sessionIds = getSessionIds(request);
    String requestedAlias = getCurrentSessionAlias(request);
    sessionIds.remove(requestedAlias);

    Cookie sessionCookie = createSessionCookie(request, sessionIds);
    response.addCookie(sessionCookie);
}

onNewSession becomes:

public void onNewSession(Session session, HttpServletRequest request, HttpServletResponse response) {
        // header part
        response.setHeader(headerName, session.getId());

        // cookie part
        Set<String> sessionIdsWritten = getSessionIdsWritten(request);
        if(sessionIdsWritten.contains(session.getId())) {
            return;
        }
        sessionIdsWritten.add(session.getId());

        Map<String,String> sessionIds = getSessionIds(request);
        String sessionAlias = getCurrentSessionAlias(request);
        sessionIds.put(sessionAlias, session.getId());
        Cookie sessionCookie = createSessionCookie(request, sessionIds);
        response.addCookie(sessionCookie);
    }

I used this in production for a browser/mobile REST API and it suits all my needs.

you can utilize spring's BeanFactoryPostProcessor ,to overwrite the postProcessAfterInitialization() to config the SessionRepositoryFilter's httpSessionStrategy by call it's setHttpSessionStrategy() method after it's initialization in spring.
