.htaccess 删除一段url并在新位置插入另一段

我正在尝试更改以下URL:：

www.example.it/ mio-pezzo- product-1-url.html --> www.example.com/product-1- my-piece- url.html
www.example.com/product-1- my-piece- url.html --> www.example.it/ mio-pezzo- product-1-url.html

我试过这样的方法：

RewriteCond %{HTTP_HOST} ^(.*)\.it$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)my-piece-(.*)$ /$1mio-pezzo-$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.com$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)mio-pezzo-(.*)$ /$1my-piece-$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.it$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)my-piece-(.*)$ /mio-pezzo-$1$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.com$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)mio-pezzo-(.*)$ /$1my-piece-$2 [L,R=301]

但这是结果

www.example.it/ mio-pezzo- product-1-url.html --> www.example.com/ my-piece- product-1-url.html
www.example.com/product-1- my-piece- url.html --> www.example.it/product-1- mio-pezzo- url.html

我怎样才能在mio pezzo之后或之前移动它？

只需在mio pezzo之后移动1美元-第一条规则如下：

RewriteCond %{HTTP_HOST} ^(.*)\.it$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)my-piece-(.*)$ /$1mio-pezzo-$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.com$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)mio-pezzo-(.*)$ /$1my-piece-$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.it$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)my-piece-(.*)$ /mio-pezzo-$1$2 [L,R=301]

RewriteCond %{HTTP_HOST} ^(.*)\.com$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)mio-pezzo-(.*)$ /$1my-piece-$2 [L,R=301]
