.htaccess，将404错误重写到其他域

问题描述：

如何将所有404错误重定向到另一个域?

How can I redirect all the 404 errors to another domain?

我找到了

Error 404 http://example.com/error.html

但是我需要:

if Error 404 (.*) http://example.com/$1

我尝试过:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ http://example.com/$1

但是它重定向所有请求，实际上，如果我运行一个.php脚本，该脚本生成带有一些404链接的页面，则该脚本的URL会变成

But it redirects all the requests, in fact if I run a .php script which generate a page with some 404 links the URL of the script becomes

http://example.com/script.php

相反，URL应该保持不变，只有404链接应该重定向到另一个域.

Instead the URL should remains the same and just the 404 links should get redirected to the other domain.

解决方案?

答

1-创建ErrorDocument指令，如下所示:

1 - Create ErrorDocument directive like this:

ErrorDocument 404 /404.php

2-然后像这样创建您的404.php:

2 - Then create your 404.php like this:

<?php
   if ($_SERVER["HTTP_HOST"] == "domain.com") // current domain
      header('Location: http://example.com' . $_SERVER["REQUEST_URI"], TRUE, 301);
?>

仅使用.htaccess进行更新:

RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^ http://example.com%{REQUEST_URI} [L,R=301]
