Redirecting subdomain to main domain keeping subdomain URL

Hello! I've been trying to redirect the domain www.thatbabyshop.co.uk to www.thatbaby.yourcheckout.co.uk , but keeping the thatbabyshop.co.uk as the URL that the customer sees.

My file directory is as follows:
-> public_html
-> catalog
-> index.php
-> thatbabyshop.co.uk
-> stokke.jpg
-> .htaccess

When I type www.thatbabyshop.co.uk/stokke.jpg the link works, and if I type www.thatbabyshop.yourcheckout.co.uk/stokke.jpg.

I've been putting mod_rewrite code in the .htaccess file in the thatbabyshop.co.uk folder, but can't seem to achieve what I want.

Any help would be much appreciated!

 

you can redirect it via cpanel redirect one
by that you can redirect it to subdomain

 

i have tried redirecting using cpanel, but can't seem to keep the original URL. Is it possible to achieve that?
