问几个cookie问题

对cookie没太多了解，看了些网上例子和介绍就开始做了些事例。但是不明白的是，开发工具每次停止后。重新运行。 cookie还是空的。这是怎么回事呢？
我本机没有清空cookie的处理

js和c#的代码都是：开发工具每次停止后。重新运行。 cookie还是空的。

难道是开发工具的临时服务器做了什么处理吗，还是项目发布后。用户访问时就是正确的。

购物车的存储重新运行。 cookie就丢失。



public static String CookieName = "SHOPPING_INFO";





	/// <summary>

	/// 添加商品进购物车

	/// </summary>

	/// <param name="productId"></param>

	/// <param name="num"></param>

	/// <returns></returns>

	public static bool AddProduct(int productId, int num) {

		HttpCookie hc = null;

		String oldCookieValue;

		String NewValue;

		hc = HttpContext.Current.Request.Cookies[CookieName];

		if (hc == null) //如果Cookie不存在 则直接新建Cookie 保存商品id和数量;

		{

			hc = new HttpCookie(CookieName);

			hc.Expires = DateTime.Now.AddDays(7);

			hc.Value = productId.ToString() + "|" + num.ToString();

		}

		else //假设Cookie存在 则处理

		{

			oldCookieValue = hc.Value;

			NewValue = AddCookieValue(oldCookieValue, productId, num);

			hc.Value = NewValue;



		}



		HttpContext.Current.Response.AppendCookie(hc);



		//Cookie写入Response  

		return true; //结束

	}



/// <summary>

	/// 获取购物车信息

	/// </summary>

	/// <returns></returns>

	public static string GetShoppingInfo() {

		HttpCookie hc = null;

		String oldCookieValue;

		hc = HttpContext.Current.Request.Cookies[CookieName];

		if (hc == null) //如果Cookie存在 则直接新建Cookie 保存商品id和数量;

		{

			return null;

		}

		else {

			return hc.Value;

		}

	}

登录票证的存储也是重新运行开发程序。cookie就丢失



//验证用户名密码

		if (new UsersDAL().IsLogin(this.txtName.Value, this.txtPwd.Value)) {





			Users userEntity = new UsersDAL().GetEntity(this.txtName.Value);



			string status = userEntity.Status.ToString();//获取登录用户的权限





			string userId = userEntity.UserID.ToString();//获取用户ID





			bool save = IsSave.Checked == true ? true : false;



			Authentication.SetCookie(this.txtName.Value, this.txtPwd.Value, status, userId, save);//填入cookie

}

	

	public static void SetCookie(string UserName, string PassWord, string Rights, string usrId, bool save) {



		String UserData = UserName + "#" + PassWord + "#" + Rights + "#" + usrId;



		//数据放入ticket

		FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, UserName, DateTime.Now, DateTime.Now.AddMinutes(60), save, UserData);

		//数据加密

		string enyTicket = FormsAuthentication.Encrypt(ticket);

		HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, enyTicket);

		HttpContext.Current.Response.Cookies.Add(cookie);
