最近剛好碰到有需要把舊網站，轉址到新網站。
為了要一次把所有連結轉到新網站。發現可以直接從 .htaccess 來處理
參考：https://linchpinseo.com/htaccess-rules/
Common 301 Redirect Htaccess Rules
How do you redirect a single page? 如果要單純轉址一個頁面
Redirect 301 /pagename.php http://www.domain.com/pagename.html
How do you redirect an entire site or domain to a new one? 如果要整個網站轉址
Redirect 301 / http://www.domain.com/
How do you redirect an entire site to a sub folder? 如果要轉址到新網站的子目錄下
Redirect 301 / http://www.domain.com/subfolder/
How do you use rewriting to redirect from an old domain to a new domain? 如果要轉址到新網站，但路徑不變似乎是可以使用這個
RewriteEngine on RewriteBase / RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]
