I have my zen cart set up in www.mydomain.co.uk/zendirectory and (for various reasons) have the site url www.shopurl.com using forwarding to get to it.

In all the config, HTTP_SERVER is set to www.mydomain.co.uk (because I had to install it that way)

What would happen if I NOW changed www.mydomain.co.uk to www.shopurl.com in the configure.php file? Would it all fall in a heap?

thanks
