更新cookie過期，沒有任何值的變化

Question

如何在每個頁面請求中簡單更新cookie的到期時間，而不會影響其值？

Answer 1

'update the User cookie expiration time on every page load 
    Dim cookieName As String = ConfigKeys.UserCookieName 
    Dim cookieExpr As String = ConfigKeys.CookieExpiration.ToString 

    '--get the cookies from request object 
    Dim userCookie As HttpCookie = HttpContext.Current.Request.Cookies(cookieName.ToUpper()) 
    '--set the expiry date 
    userCookie.Expires = DateTime.Now.AddMinutes(Integer.Parse(cookieExpr)) 
    '--add the updated cookies back to Response object 
    HttpContext.Current.Response.Cookies.Add(userCookie) 

Answer 2

HttpContext.Current.Response.Cookies["MyCookie"].Expires = 
    DateTime.Now.AddDays(1) 

或將其設置爲最大，忘了過期：

HttpContext.Current.Response.Cookies["MyCookie"].Expires = 
    DateTime.MaxValue
