Q. How to add and delete Cookie in jsp ?
Add Cookie to response object:
Cookie cookie = new Cookie ("name",value);
cookie.setPath("/");
cookie.setDomain(DOMAIN_NAME); DOMAIN_NAME may be .techfaq360.com
cookie.setMaxAge(2* 7 * 24 * 60 * 60);// 2 week
response.addCookie(cookie);
Get cookie from request object :
Cookie myCookie = null;
Cookie cookies [] = request.getCookies ();
if (cookies != null)
for (int i = 0; i < cookies.length; i++)
{
if (cookies [i].getName().equals ("name")) // the name of the cookie you have added
{
myCookie = cookies[i];
break;
}
}
Delete Cookie:
You can't delete the cookie. just add maxage to 0;
cookie.setMaxAge(0);
cookie.setPath("/");
cookie.setDomain(DOMAIN_NAME);
response.addCookie(cookie);
cookie.setMaxAge(-1) means on browser close cookie will be deleted.
