Forwarding a domain instead of parking a domain

[druffus]

I have an additional domain name for my site. I set it up as a parked domain, but is causing some problems with my e-commerce system and adding products.

I would like to create a forward to the main domain name instead of being a parked domain. The only way i can think to do it is to create another account and put a page in it that forwards, but I am sure there has to be another way, cause that seems sloppy.

I am using RHE with CPanel.

Thanks for any help.
