When to use Request.Cookies over Response.Cookies?

Question

Do I use response when at a page event (e.g. load) as this is a response from ASP.NET, and request when pressing a button as this is a response going to ASP.NET for processi

Answer 1

Andrew's Code gave an error in "AllKeys.Contains" Method. So I corrected a little..

public void WriteCookie(string strCookieName, string strCookieValue)
    {
        var hcCookie = new HttpCookie(strCookieName, strCookieValue);
        HttpContext.Current.Response.Cookies.Set(hcCookie);
    }


    public string ReadCookie(string strCookieName)
    {    
        foreach (string strCookie in HttpContext.Current.Response.Cookies.AllKeys)
        {
            if (strCookie == strCookieName)
            {
                return HttpContext.Current.Response.Cookies[strCookie].Value;
            }
        }         

        foreach (string strCookie in HttpContext.Current.Request.Cookies.AllKeys)
        {
            if (strCookie == strCookieName)
            {
                return HttpContext.Current.Request.Cookies[strCookie].Value;
            }
        }

        return null;
    }
