处理404错误与重定向到主页的最佳方法 [英] Best way to handle 404 error with redirect to homepage
问题描述
我已经搜查，读了很多，但还是没能找到一种方法，来实现我的目标。现在，我甚至觉得这是不可能的。是吗？
I've searched, read a lot, but still couldn't find a way, to achieve my goal. Now I even think it is impossible. Is it?
我要404错误，处理不当，所以我有的ErrorDocument 404 /404.php 在.htaccess文件中，我要发出正确的头搜索引擎标题（HTTP / 1.1 404未找到）忘记页面，同时我想我的访问者到 /index.php?$c$c=404 这样我就可以告诉他有关他在找什么的，是不可用，但还是让他在网站上。
I want 404 errors to handled properly so I have ErrorDocument 404 /404.php in the .htaccess file, and I want to send out the right header to search engines header("HTTP/1.1 404 Not Found") to forget that page, also I want to redirect my visitor to /index.php?code=404 so I can inform him about that what he was looking for is not available, but still keep him on the site.
现在看来一切都很好，直到我想将用户重定向：那么服务器发出一个302的消息，这将覆盖我的previous 404头，因此，虽然我可以将用户发送到需要的地方，我还是不能告诉searchbots该地址是错误的。
Now it seems everything is fine, until I want to redirect the user: then the server sends out a 302 message, which overwrites my previous 404 header, so while I can send the user to the desired place, I still can't tell the searchbots that the address is wrong.
如果我添加一个包括：（的index.php？code = 404）标题行，它只是将无法正常工作后，服务器说，文件不存在。
If I add a include("index.php?code=404") after the header line it just won't work, the server says that file does not exist.
我应该怎么办？
推荐答案
尝试是这样的：
<?php
header("HTTP/1.0 404 Not Found");
echo '<html>
<head>
<meta http-equiv="Refresh" content="0;url=http://www.mysite.com/index.php?code=404" />
</head><body></body>
</html>';
?>
我使用的是元重定向，否则你得到的头已经发送的错误。
I'm using a meta redirect because otherwise you get an error that headers have already been sent.
我使用招测试了在本地主机上，并得到了适当的404响应，然后正确地重定向到不同的页面成功。
I tested this on localhost using Fiddler, and got a proper 404 response, and then was correctly redirected to a different page successfully.
