I want to update the browser cookie before page response ended. basically, i want to update cookie continuously and access this cookie on some other methods but it did not update until response.end() method is executed. so give me some alternate solution.


Thanks.

What I have tried:

For Create Cookie

var DBCookie = new HttpCookie("CookieName")
DBCookie["ID1"]="1";
DBCookie["ID2"]="2";
DBCookie["ID3"]="3";
DBCookie.Expires = DateTime.Now.AddMinutes(60);
HttpContext.Current.Response.Cookies.Add(DBCookie);

For Update Cookie

var DBCookieOld = HttpContext.Current.Request.Cookies["CookieName"];
DBCookieOld["ID1"]="4";
DBCookieOld["ID2"]="5";
DBCookieOld["ID3"]="6"
DBCookieOld.Expires = DateTime.Now.AddMinutes(60);
HttpContext.Current.Response.Cookies.Add(DBCookieOld);
