怎么在ajax的ashx 文件中获取cookie

[xlz923]

在后台页面 中可以使用cookie HttpCookie IPAddressCookie =Request.Cookies["IPAddressCookie"];
IPAddressCookie = new HttpCookie("IPAddressCookie");
IPAddressCookie.Values["IPAddress"] = WebHelper.Pages.Request.GetIP();
IPAddressCookie.Expires = DateTime.Now.AddHours(1);
Response.Cookies.Add(IPAddressCookie);

但是在ashx中提示找不到request.cookie
谁能给个设置cookie的代码例子

context.Request

ashx里是不是传递了httpcontex或httpapplication类似的参数啊，它们上边有属性可以取到Request对象，或者HttpContext.Current.Requst， 后台页面的Request是它的一个属性，它的类型是HttpRequest吧

context.Request

HttpCookie IPAddressCookie = System.Web.HttpContext.Current.Request.Cookies["IPAddressCookie"];这样也不行的。。

HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(requestURL);
                myRequest.Method = "post";

//开始提取站点cookie的信息
                String[] arr1 = Request.Cookies.AllKeys;
                StringBuilder cookieStr = new StringBuilder();
                for (int i = 0; i < arr1.Length; i++)
                {
                    HttpCookie hc = Request.Cookies[arr1[i]];
                    if ((hc.Name != null) && (hc.Value != null))
                    {
                        cookieStr.Append(hc.Name + ",");
                    }
                }
                if (cookieStr.Length > 1)
                {
                    cookieStr.Remove(cookieStr.Length - 1, 1);
                }
                Uri uri = new Uri(ConfigurationHelper.GetAppSettings("Uri_Value"));

//CookieContainer使用之前必须new一个，否则是NULL的
                myRequest.CookieContainer = new CookieContainer();

//在SetCookie方法中，传入的Cookie是站点cookie的key集合，通过逗号分隔
                myRequest.CookieContainer.SetCookies(uri, cookieStr.ToString());
                myRequest.Timeout = 300000;
                HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

楼上的我看过。不过有几个地方不懂，能注释一下么
1HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(requestURL);
requestUrl 要写具体地址么

2 Uri uri = new Uri(ConfigurationHelper.GetAppSettings("Uri_Value"));
这句话代表什么。

3
myRequest.CookieContainer.SetCookies(uri, cookieStr.ToString());

		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;
		}

public void ProcessRequest(HttpContext context)

context.Response.ContentType = "text/plain";
context.Response.Write("foo="+context.Request.Cookies["IPAddressCookie"];);
