[Question] How do I redirect a domain ?

[Matador]

Nvm. I fixed it provisorily using a subdomain.


[I decided to buy a domain at GoDaddy today.
The thing I wanted is that if people visit www.X.net they get redirected to www.Z.net .

And since I'm not that horribly retarded, I actually succeded! Yaaay!
I used the giant multicolored "Forward Your Domain" button in the middle of the GoDaddy account panel to do that..

But now - if I upload a file to the hosting of my domain like www.X.net/index.php , I'm being forwarded to www.Z.net/index.php , which doesn't exist.

So: How can I redirect people visiting www.X.net to www.Z.net without redirecting people, who try to access a hosted file like www.X.net/index.php to www.Z.net/index.php ?
Or: How can I limit the redirection to only the front page?

This is one hell of an amateurish question, but I can't seem to find the ****ing answer.

Much appreciated!]
