You can redirect your website to another by using RewriteRule in .htaccess.

If your website URL is example.eu, it can be redirected to another URL example.ch using htaccess.
If suppose your URL is example.eu/blog then the URL will be redirected to the same page.

RewriteCond %{HTTP_HOST} !^m\.
RewriteRule ^$ http://example.eh [R,L]
