IIS二级域名

1、两个网站 

2、test1设置ip为本地地址，设置域名test1.com，端口号默认为80，如果设置IP后就不用设置端口

3、test2设置域名为test2.test1.com，端口默认80，IP地址和一级域名的IP一样

4、注意事项

ip地址不能为空

5、cookie共享设置

5-1、test1.com域名下，添加cookie

public ActionResult addCookie(string key,string value)
        {
            Response.Cookies.Add(new HttpCookie("name", "gooney") { Expires=DateTime.Now.AddMinutes(1)});

            HttpCookie cookie = new HttpCookie(key);
            cookie.Path = "/";
            cookie.Domain = "test1.com";
            cookie.Expires = DateTime.Now.AddMinutes(5);
            cookie.Value = value;
            Response.Cookies.Add(cookie);
            return View();
        }

5-2、test2.test1.com获取cookie

public ActionResult getCookie(string key)
        {
            string value = Request.Cookies[key].Value;
            return View("getCookie",string.Empty, value);
        }
