Can`t loggin with Redirect but can logging with Redirect with No Frame

[Guest]

I use directnick with my domain register: http://www.sardineroinformatica.com

 

And I redirect the domain to web space where is instaled the oscommerce in a subdomain: http://mayorista.compummerce.com

 

If i use the redirect with no frame i can logging, but in the direction address, I can see the complete address with the subdomain: http://mayorista.compummerce.com, and i dont want that.

 

If i use redirect i can't loggin, but i see http://www.sardineroinformatica.com

 

There is any way I can see in the whole web http://www.sardineroinformatica.com, but the system permits to logging

 

regards
