Image map pointing to different files

[Tim D. Hansen]

Hi
I want an area in an Image Map to point to a file depending om the URL in the browser.

one example

I´m using my imagemap on the page http://www.something.com/1/ here i want the area to point to:

http://www.something.com/1/document.pd

on the page http://www.something.com/2/ i´m using the same image map, but this time i want the same area to point to

http://www.something.com/2/document.pd

Notice that the filenames are the same

Is this possible - and could you give me som directions pleas

Thanks Tim
