href redirection

[Murty]

Hey guys,
I'm fairly noob when it comes to programming, so im not 100% sure on how to word this, but ill give it a whirl.

I want to use my forum header and footer in a different URL extension (eg forum installed at 'http://forums.mysite.com/' and i want to use the header and footer template from there, for this link 'http://forums.mysite.com/ext/').

But I tried just copying and pasting the code, but obviously it comes up with broken images and it cant find the phrases (it is trying to get images and phrases from 'http://forums.mysite.com/ext/' rather than 'http://forums.mysite.com/'). So i was wandering if there is some way i can redirect the href that its looking for or something like that? so its looking in 'http://forums.mysite.com/' rather than 'http://forums.mysite.com/ext/'

Any help is awesome, thanks
