1.找到web.config配置文件
2.制作出错页error.htm，代码如下
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>出错拉~~~</title>
<link href="css/login.css" rel="stylesheet" type="text/css" />
<script language="javascript" type="text/javascript">
var i = 5;
var intervalid;
intervalid = setInterval("fun()", 1000);
function fun() {
if (i == 0) {
window.location.href = "default.aspx";
clearInterval(intervalid);
}
document.getElementById("mes").innerHTML = i;
i--;
}
</script>
</head>
<body>
<div id="errorfrm" class="round1">
<h3>出错啦~~~</h3>
<div id="error">
<img src="images/error.gif" alt="" />
<p>系统出错，请联系管理员</p>
<p>将在 <span id="mes">5</span> 秒钟后返回首页</p>
</div>
<div id="footer">
