假如是虚构主机中要设置404错误的页面
请用动态页面asp或PHP，多么本事精确放回404粗偶的消息，设置为html或htm返回的是200消息
在asp代码上加入：
<%Response.Status = "404 Not Found"%>
在PHP代码上加入：
<?php
header('HTTP/1.1 404 Not Found');
?>
就能了
如：
<?php
header('HTTP/1.1 404 Not Found');
?><html>
<head>
<META http-equiv=Content-Type content="text/html; charset=gb2312">
<meta http-equiv="refresh" content="2;URL=http://www.sv11.cn/">
<title>404 Not Found</title>
<style type="text/css">
