为什么setmaxage不允许更长的时间超过〜5mins [关闭]

Question

In my jsp file I am setting a cookie I want to persist for a year. I have used the set max age and multiplied my seconds so it is a year. However the cookie only lasts for around 5mins. Even if I put in a ridiculously large value it still only lasts for ~5mins.

I am testing on localhost could that have anything to do with it?

Code below:

    //value to check if the EU compliance cookie is present
boolean euCookiePresent = false;
//cookie parameters
String cookieName = "wtr_ca";
String cookieValue = "1";
int cookieExpiry = 365;

//cookie expiary is in seconds so convert to days
cookieExpiry = cookieExpiry * 60 * 60 * 24;

//Get clients cookies
Cookie cookies [] = request.getCookies ();

if (cookies != null){
    //iterate over users cookies to check for euCookie
    for (int i = 0; i < cookies.length; i++) 
    {
        if (cookies [i].getName().equals (cookieName)){
            euCookiePresent = true;
            break;
        }
    }

}

if (euCookiePresent == false){
    //no EU Cookie found therefore place it on client
    response.setContentType("text/html");
    Cookie cookie = new Cookie(cookieName,cookieValue);

    //cookie expiary is in seconds so convert to days
    cookie.setMaxAge(cookieExpiry);
    response.addCookie(cookie); 
}

Answer 1

cookie.setMaxAge(60*60*24);

sets the max age to about 1 hour, no a year

what you are trying to do is:

cookie.setMaxAge(cookieExpiry);

由于某种原因，Maven不再将我的新代码放置在服务器上，因此它仍使用我的365秒，而不是将它转换为几天的更新代码。
