问题描述
我在用asp.net做测试时发现设置cookie的domain属性后添加cookie，传值到其他页面时domain属性无法正常读出，但是其他属性都可以读出来，不知道为什么？测试代码如下：----------------------------------publicpartialclass_Default:System.Web.UI.Page{protectedvoidPage_Load(objectsender,EventArgse){if(!IsPostBack){//HttpCookiecookie=newHttpCookie("UserInfo");//cookie.Value="name";//cookie.Domain="domain";//Response.Cookies.Add(cookie);CookiesOperate.setCookie("UserNameCookie2","seek2",1,".127.0.0.1");}Button1.Click+=newEventHandler(Button1_Click);}voidButton1_Click(objectsender,EventArgse){//TextBox1.Text=Request.Cookies["UserNameCookie2"].Domain;Response.Redirect(@"//127.0.0.1/test/2.aspx");}}publicclassCookiesOperate{///<summary>///信息写入cookie///</summary>///<paramname="key">cookie名</param>///<paramname="value">cookie值</param>///<paramname="timeout">过期时间,0表示cookie默认的过期时间</param>publicstaticvoidsetCookie(stringkey,stringvalue,inttimeout,stringdomain){try{HttpCookiecookie=newHttpCookie(key);value=HttpUtility.UrlEncodeUnicode(value);cookie.Value=value;if(timeout!=0)cookie.Expires=DateTime.Now.AddDays(Convert.ToInt32(timeout));if(!String.IsNullOrEmpty(domain)){cookie.Domain=domain;}HttpContext.Current.Response.Cookies.Add(cookie);}catch{}}}-----------------------------------------------------------------------------------2.aspxpublicpartialclass_:System.Web.UI.Page{protectedvoidPage_Load(objectsender,EventArgse){Response.Write("Domain:"+Server.HtmlEncode(Request.Cookies["UserNameCookie2"].Domain));}}-----------------------------------------------------------------------还请专家解释！
解决方案
解决方案二：
浏览器根据Domain来判定传不传Cookies但不传Domain这个数据
解决方案三：

现在的问题是用户无法正常注销，我测试后发现是没有办法获得Domain域。请问应该怎么改？
解决方案四：
你设置cookieDomain="diybl.com";所有的二级域名就可以用你调协的Cookies
解决方案五：
你设置cookieDomain="diybl.com";所有的二级域名就可以用你的Cookies
解决方案六：
我的问题是注销的时候没办法注销啊！
解决方案七：
注销代码看下
解决方案八：
就是最下面那段===============================删除cookie=====================================CookiesOperate.KillCookie("UserNameCookie");CookiesOperate.KillCookie("BBSUserCookie");CookiesOperate.KillCookie("WbUserCookie");
