重定向301個不存在的文件（pdf，doc）等

Question

我有一個基於Drupal CMS的網站，其中的文件經常被刪除。爲了保留他們的反向鏈接，我希望不存在的pdf和word文件重定向到某個通用頁面，通知他們的刪除。

這是正確的方法嗎？ ：

（從301 Redirects on any non existent image, pdf or url using .htaccess拾起）：

RewriteEngine on 
RewriteBase/

RewriteCond %{REQUEST_FILENAME} !-d # not a dir  
RewriteCond %{REQUEST_FILENAME} !-f # not a file 
RewriteRule ^.*\.(pdf|doc|xls|xlsx|docx|zip)$ show-deleted-page.htm [R=301,L] 

這裏是它需要我的Drupal的.htaccess文件的工作：

# 
# Apache/PHP/Drupal settings: 
# 

# Protect files and directories from prying eyes. 
<FilesMatch "\.(engine|inc|info|install|make|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl)$|^(\..*|Entries.*|Repository|Root|Tag|Template)$"> 
    Order allow,deny 
</FilesMatch> 

# Don't show directory listings for URLs which map to a directory. 
Options -Indexes 

# Follow symbolic links in this directory. 
Options +FollowSymLinks 

# Make Drupal handle any 404 errors. 
ErrorDocument 404 /index.php 

# Set the default handler. 
DirectoryIndex index.php index.html index.htm 

# Override PHP settings that cannot be changed at runtime. See

    <FilesMatch \.php$> 
    # Do not allow PHP scripts to be cached unless they explicitly send cache 
    # headers themselves. Otherwise all scripts would have to overwrite the

# Various rewrite rules.

Answer 1

RewriteEngine on 
RewriteBase/

RewriteCond %{REQUEST_FILENAME} !-d # not a dir  
RewriteCond %{REQUEST_FILENAME} !-f # not a file 
RewriteRule ^.*\.(pdf|doc|xls|xlsx|docx|zip)$ http://example.com/show-deleted-page.htm [R=301,L] 

剛剛測試過了，它作品。確保你的包含你的域名，因爲Apache試圖在該URL找到一個「物理」文件。
