前段时间网站层级架构做了调整,造成许多已收录的链接变成了死链接,虽已设置了404页面,可是百度仍然没有更新死链收录情况,后细查原来是http状态返回码仍然是200,之后咨询了售后服务工程师得知此设置。
404.asp
<!doctype html>
<html>
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<%Session.codePage=65001%>
<% Response.Charset = "utf-8" %>
<% Response.Status = "404 Not Found" %>
<head>
<meta charset="utf-8">
<meta http-equiv="refresh" content="10; URL=/" />
<title>网页或文件未找到</title>
</head>
<body>
<script type="text/javascript" src="http://www.qq.com/404/search_children.js" charset="utf-8" homePageUrl="/" homePageName="返回首页"></script>
</body>
</html>
已添加这一段代码和修改为404.asp
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<%Session.codePage=65001%>
<% Response.Charset = "utf-8" %>
<% Response.Status = "404 Not Found" %>
在 IIS 重新指向404.asp
效果图:
