1）站点1，创建Cookie

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace WebApplication1{    public partial class Default : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            if (!IsPostBack)            {                //设置Cookie                HttpCookie myCookie = new HttpCookie("MyCook");//初使化并设置Cookie的名称                DateTime dt = DateTime.Now;                TimeSpan ts = new TimeSpan(0, 0, 1, 0, 0);//过期时间为1分钟                myCookie.Expires = dt.Add(ts);//设置过期时间                myCookie.Values.Add("LoginName", "Admin");                Response.AppendCookie(myCookie);            }        }        /// <summary>        /// 获取Cookie        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        protected void btnTestCookie_Click(object sender, EventArgs e)        {            HttpCookie myCookie = HttpContext.Current.Request.Cookies["MyCook"];            if (myCookie != null)            {                string LoginName = myCookie["LoginName"];            }        }    }}

2）站点2，跨域获取Cookie

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace WebApplication2{    public partial class Default : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            HttpCookie myCookie = HttpContext.Current.Request.Cookies["MyCook"];            if (myCookie != null)            {                string LoginName = myCookie["LoginName"];            }        }    }}
