JS脚本判断是否支持Cookie，C#读取设置Cookie

JAVASCRIPT判断IE是否开启COOKIE 

<script type="text/javascript">
 
      function CookieEnable()
      {
        var result=false;
        if(navigator.cookiesEnabled)
          return true;
        document.cookie = "testcookie=yes;";
        var cookieSet = document.cookie;
        if (cookieSet.indexOf("testcookie=yes") > -1)
          result=true;
        document.cookie = "";
        return result;
      }
 
      if(!CookieEnable())
      {
        alert("对不起，您的浏览器的Cookie功能被禁用，请开启");
      }
</script>

asp.net cookie              

HttpCookie ck = Request.Cookies["cktest"];
if (ck == null)
{
    ck = new HttpCookie("cktest");
    ck.Value = "123";

    ck.Expires = DateTime.Now.AddSeconds(20);//20秒的有效期
    Response.Cookies.Add(ck);
    Response.Write("new ck");
}
else
{
    Response.Write(ck.Value.ToString());
}

//在一个Cookie中储存多个信息
/**//**//**//*
HttpCookie cookie = new HttpCookie("cktest");
cookie.Values.Add("v1","1");
cookie.Values.Add("v2","2");
cookie.Values.Add("v3","3");
Response.AppendCookie(cookie);


HttpCookie cookies = Request.Cookies["cktest"];
string value1 = cookies.Values["v1"];
string value2 = cookies.Values["v2"];

Response.Write(value1 + value2);
