IHttpModule访问Cookie解决思路

IHttpModule访问Cookie
public   class   ACookies:   System.Web.IHttpModule,   System.Web.SessionState.IRequiresSessionState{
public   void   Init(HttpApplication   context)
                {
                        context.PreRequestHandlerExecute   +=   new   System.EventHandler(onPreRequestHandlerExecute);
                }

                public   void   onPreRequestHandlerExecute(object   sender,   System.EventArgs   e)
                {
                        HttpApplication   application   =   (HttpApplication)sender;
                        HttpContext   context   =   application.Context
                        System.Web.HttpCookie   cookie   =   new   System.Web.HttpCookie( "A ");
                                cookie.Domain   = "MySite.com "
                                DateTime   dt   =   DateTime.Now;
                                cookie.Expires   =   dt.AddMinutes(100);
                                cookie.Values.Add( "USERID ",   "123456 ");
                                context.Response.AppendCookie(cookie);
                }
}

}
上面这样好像不能不写入Cookies,同样测试读取Cookies似乎也不能.请问路过大侠有无解决方案?

Cookie应该有用的。

这跟ASP.NET角色授权差不多，Cookie应该起作用的。

我测试了一下，有的啊！
我在global.asax中测试，Cookie使用正常啊

global.asax:
void Application_PreRequestHandlerExecute(object sender, EventArgs e)
{
System.Web.HttpCookie cookie = new System.Web.HttpCookie( "A ");
DateTime dt = DateTime.Now;
cookie.Expires = dt.AddMinutes(100);
cookie.Values.Add( "USERID ", "123456 ");
System.Web.HttpContext.Current.Response.AppendCookie(cookie);

}

aspx.cs:
if (Request.Cookies[ "A "] != null)
Response.Write(Request.Cookies[ "A "][ "USERID "]);
else
Response.Write( "NO COOKIE ");

[解决办法]
cookie.Domain = "MySite.com "
测试的域名有没有也是MySite.com?
要一样的才行哦

貌似很复杂。
