我以这种方式在sharepoint webpart中保存一个cookie：
- System.Web.HttpCookie cookie = new System.Web.HttpCookie(_cookieApplicationId);
- cookie[_cookieName] = value;
- cookie.Expires = DateTime.Now.AddMonths(1);
- HttpContext.Current.Response.SetCookie(cookie);
该cookie始终成功保存.我可以使用firebug在客户端上看到它.
当我尝试读取该cookie时：
- System.Web.HttpCookie cookie = HttpContext.Current.Request.Cookies[_cookieApplicationId];
- return cookie[_cookieName];
