Help in problem domain + website

[tnlsolutions]

Hi all,
I'm using shared hosting account in JaguarPC and I have one question:
My primary domain is tnlsolutions.com, and I added one other domain to Jaguar account, is duantinhoc.com . I put alot of websites in duantinhoc/Clients folder ( for example http://www.duantinhoc.com/Clients/mobicheck ) , now I want the set up when users type http://www.tnlsolutions.com/Clients/mobicheck , then they can still see this website but real address is http://www.duantinhoc.com/Clients/mobicheck

Thanks for your help.

TNLSolutions.com

In .htaaccess do something like this:

RedirectMatch 301 ^Clients/(.*)$ http://www.duantinhoc.com/Clients/$1

This will do a 301 (permanent) redirect (which basically tells search engines to index the destination URL only) any time someone tries to use a tnlsolutions.com/Clients address, forwarding them to an identical address on duantinhoc.com instead.
