ashx中session cookies无法清除

Question

<%@ WebHandler Language="C#" Class="ashx_LoginOut" %>using System;
using System.Web;public class ashx_LoginOut : BaseHttpHandler
{    public override void ProcessRequest(HttpContext context)
    {
        try
        {
            base.ProcessRequest(context);            Response.ContentType = "text/plain";
            Session.Clear();
            context.Session["ccSouTiInfo"] = null;
            HttpCookie cookies = context.Request.Cookies["UserInfo"];
            context.Session.Abandon();//结束会话
            context.Session.Clear();//清空session
            if (cookies != null)
            {
                HttpCookie cookie = null;
                cookie = context.Request.Cookies["UserInfo"];
                cookie.Expires = DateTime.Now.AddDays(-19);
                context.Response.Cookies.Add(cookie);
            }            Response.Cookies.Clear();
            WriteLog(string.Format("{0}退出登陆", this.user.DisplayName));
            WriteSuccess();
        }
        catch (Exception ex)
        {
            WriteError(ex.Message);
        }
    }}
这样处理以后 session cookies中的UserInfo 仍然存在，解决很长时间了没搞定，求大家帮忙

Answer 1

设置 cookie 使用 context.Response.Cookies["UserInfo"]，读取 cookie 才使用 context.Request.Cookies["UserInfo"]。不要使用同一个东西。

                cookies.Expires = DateTime.Now.AddDays(-19);
                context.Response.Cookies.Add(cookies);
                //context.Response.Cookies.a
            }            Response.Cookies.Clear();
            WriteLog(string.Format("{0}退出登陆", this.user.DisplayName));
            WriteSuccess();
        }
        catch (Exception ex)
        {
            WriteError(ex.Message);
        }
    }}您好，这个问题已经困扰好几天了现在context.Request.Cookies["UserInfo"];读取是用的request，设置是用的response，还是不行呢？

你这是服务器端代码，没有什么“清除cookie”这一说。正确地设置 Response.Cookie，不要清除。
