ASP.NET系统退出（移除Session 、清除浏览器缓存）

一、在退出时移除Session，首先在登录时要记录登录信息

Session["id"] = user.id.ToString();

Session["name"] = user.name.ToString();

Session["pwd"] = user.password.ToString();

Session["time"] = user.LoginTime.ToString();

Session["limit"] = user.limits.ToString();

二、当点击退出系统时，移除Session，清除缓存

public void Clear(object sender, EventArgs e)
    {
        Session["id"] = null;
        Session["name"] = null;
        Session["pwd"] = null;
        Session["time"] = null;
        Session["limit"] = null;
        ClearClientPageCache();
        Response.Redirect("~/Login.html");
    }
    public void ClearClientPageCache()
    {
        //清除浏览器缓存
        Response.Buffer = true;
        Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
        Response.Cache.SetExpires(DateTime.Now.AddDays(-1));
        Response.Expires = 0;
        Response.CacheControl = "no-cache";
        Response.Cache.SetNoStore();
    }             

三、

<a  target="_self" runat="server"  onserverclick ="Clear"  >退出</a>
