在htaccess（wordpress）中将较长url的规则重写为较短url

现在，完整的url如下所示：

website.com/en_us/multimedia/blogs/podcast/2011/08/post title/

我想把上面的url缩短为这个：

website.com/podcast/2011/08/post title/

与搜索引擎优化友好的301重定向

有人能给我一些建议吗

谢谢大家!

我当前的.htaccess文件如下：

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

---

要从

website.com/en_us/multimedia/blogs/podcast/2011/08/post title/

重定向到

website.com/podcast/2011/08/post title/

请在存在任何其他规则之前，将以下内容添加到.htaccess文件中

RewriteEngine on
RewriteBase /

RewriteCond %{REQUEST_URI} ^/en_us/multimedia/blogs/(.+)$ [NC]
RewriteRule . http://%{HTTP_HOST}/%1 [L,R=301]
