Wild card configuration for URL languages

I need to set a header for origins and one of the domains/URL I need to allow access is order.subdomain.com

In my server file, I will have var someURL = https://order.somedomain.com but depending on the locale, there might language abbreviations appended to it such as https://french.order.subdomain.com. I was thinking of doing https://*.order.subdomain.com but not sure if this is the correct way to do it

Do I not even have to worry about this and can I just do var someURL = https://order.somedomain.com and that will take care of all the language url prefixes?
