<iframe id="fresh" src="Refresh.aspx" width="0" height="0"></iframe>
然后在Refresh.aspx代码如下:
<head runat="server">
<title></title>
<meta http-equiv="Refresh" content="600; url=Refresh.aspx" /> (表示定时600秒刷新到Refresh.aspx)
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
protected void Page_Load ( object sender,EventArgs e )
{
// 访问Session以防止Session过期
Session["Refresh"] = string.Empty;
}
