Browse through the web using a subdomain

Hello,

I am not sure if I can ask this question here.

We have:

• a WHM
• an account

We would like that, ADDITIONALLY, we could browse through the web using a subdomain "hot": https://www.hot.dog.tld/

So, this:
https://www.dog.tld/category/article.html

is the same as this:
https://www.hot.dog.tld/category/article.html

In cpanel I have tried several things (subdomain, alias, redirect...) but it does not work,

Could you tell me how to do it or where to read about it?

Thanks in advanced.

 

Thanks.

My hosting provider tell me at first: "that is not possible"
My second attempt: "create a redirection"
My third attempt: "create a subdomain pointing to root directory"

I am not sure, but i think no one of this options is correct...

 

Perfect. Thank you

(I must delete the redirection)

Pd: know looking for set the canonical url to avoid duplicated content

(I LOVE CPANEL, and know i love cpanel forum too)
