If a page on your website no longer exists and you want to redirect it to a new page or website, you can use the dot htaccess file to redirect visitors.
Redirect from a page/directory to another domain or the main domain:
Redirect from a specific page to a domain:
RewriteEngine on
Redirect 301 /mypage.html http://example.com
Redirect from one page to another page
#Redirect from a page/directory to another page
Redirect 301 /oldpage.html /newpage.html
Whenever you open a URL such as example.com/oldpage.html, it will redirect you to example.com/newpage.html.
