Static directory url to static php url

[MAX232]

hi all,

I've browsed through the forum for an hour now but I can't find my solution. What I want is redirect directory url to preset php urls. e.g.

http://www.mysite.com/news/

Must always go to:

http://www.mysite.com/index.php?id=1

And

http://www.mysite.com/forum/

Must always go to:

http://www.mysite.com/index.php?id=2

Could someone give me a hand on this one?

MAX
