更新JSESSIONID Cookie值

Question

I am trying to update the JSESSIONID value as below but its creating a new JSESSIONID cookie for each request.

    Cookie[] cookies = httpRequest.getCookies();
    Cookie jsessionCookie = null;
    Cookie hazelcastCookie = null;
    if (cookies != null) for (Cookie cookie : cookies) {
        if (cookie.getName().equals(JSESSION_COOKIE_NAME))
            jsessionCookie = cookie;
        else if (cookie.getName().equals(HAZELCAST_COOKIE_NAME)) hazelcastCookie = cookie;
    }
    if (jsessionCookie != null && hazelcastCookie != null
            && jsessionCookie.getValue() != hazelcastCookie.getValue()) {
        jsessionCookie.setValue(hazelcastCookie.getValue());
        httpResponse.addCookie(jsessionCookie);
        LOGGER.log(Level.DEBUG,
                "Updated jsessionCookie value with  hazelcastCookie --> " + jsessionCookie.getValue());
    }

What change I should make to just update the JSESSIONID value instead of creating a new one for each request?

UPDATE

Answer 1

If you want to set the value of an existing cookie, the following fields of the cookie must all be the same:

1. domain
2. path
3. secure
4. http-only
5. name
