DNS-newbie question...

[Runar]

Is it possible to give different domain-names to different directories
on the same server?

For example:
On my server I would like make two directories; /dir1 and /dir2. Then I
would like references to the adress "www.dir1.com" to read files from
/dir1 and references to "www.dir2.com" to get files from /dir2.

If this is possible, how is it done, ie. what do I put in my
"zone-files"?
