Subdomain redirection question

I have a subdomain like http://sub.domain.com/ which is pointing to http://www.domain.com/sub

I had created this from cPanel and it works. But when I entered http://sub.domain.com/ to address bar and hit enter the address also changes to http://www.domain.com/sub

The problem is that I want it still remain as http://sub.domain.com/
What should I do ? (mod_rewrite ?) Thanks in advance.

 

It seems like you've configured a redirect, not a subdomain.

 

you can redirect it to your main website and let index.php take care of the redirections.

see the knowledge base of brinkster.com

 

Just remove the redirection for your created submain and it will work.

 

I have godaddy and i had the same problem, i just had to "MASK" the sub domain.
Something like that.
