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>
