简单的apache重定向

Question

如何将所有图像从www.example.com和example.com重定向到images.example.com？

下面是一些代码，我在网上找到，但我不明白很多，如预期

#step 1 redirect ALL images from any domain to images.example.com 
RewriteCond %{REQUEST_URI} ^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC] 
RewriteRule ^(.*)$ http://images.example.com/$1 [L,R=301] 

#step 2 redirect non www to www 
RewriteCond %{HTTP_HOST} ^example.com$ [NC] 
RewriteRule (.*) http://www.example.com/$1 [R=301,L] 

#step 3 redirect ALL non images from images.example.com to www.example.com 
RewriteCond %{REQUEST_FILENAME} !\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC] 
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] 

任何帮助将非常感激这是行不通的！

谢谢！

如果要将所有图像重定向到子域，请执行此操作。

RewriteEngine On 
RewriteCond %{REQUEST_URI} ^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC] 
RewriteRule ^(.*)$ http://images.example.com/$1 [L,R=301] 

RewriteCond %{HTTP_HOST} ^images\.example\.com [NC] 
RewriteCond %{REQUEST_URI} !^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC] 
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
