On a Linux server you would use your .htaccess file to implement a 301 redirect for your pages. We’ll now show you how to edit the .htaccess file, then go over the different redirect options. Sample of code from example.com domain’s .htaccess file:
RewriteEngine on

RewriteCond %{HTTP_HOST} ^experts.ng [NC,OR]
RewriteCond %{HTTP_HOST} ^www.experts.ng [NC]
RewriteRule ^(.*)$ https://expertsclan.com//$1 [L,R=301,NC]
