How to set up a site admin redirect?

Question

htaccess

There was a need to change the site admin url, for example, to move from admin.old.ru to admin.new.ru without transferring the code. As far as I understood from the information in Google, the problem can be solved using redirects by making changes to the htaccess file.

Answer 1

Yes, you can make changes to the htaccess file or one of the admin files.
Here are a couple of examples in different languages:
.htaccess with url wrapping

RewriteEngine on 
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=301,L]

PHP without url wrapping HTTP without url wrapping JS(browser) without url wrapping JS(browser) without url wrapping - option 2 Choose which one suits you best.

window.location.href = "http://admin.new.ru";
window.location.replace( "http://admin.new.ru");
