Lack of interest Redirect index to homepage

[bart]

I want to have a custom homepage, but without all the extra's as in the portal-addons and the homepage-addon.

I really just want to have people redirected this way:

http://xenforo.com/ or http://xenforo.com/index.php
=>
http://xenforo.com/page/mypage

best would be if the addressbar still read http://xenforo.com/

I prefer doing it without an extra addon. So maybe through htaccess, but I can't seem to get that right...

Any suggestions?
