I concur with DrBytes' recommendation that that parking the domain onto your existing hosting account so that it's basically an alias to your primary domain is the smartest most efficient solution.
This is done in five easy steps.
1. Log into your cPanel
2. Click on the 'parked domains' icon
3. Enter the name of the parked domain.
4. Set the path to match your main domain
5. Save
Cheers
