Jacqueline,

This cannot be done unless you control the web server. A *lot* of web 
servers now-a-days are not Apache (and its derivatives), but rather 
routing servers like Django, Happstack, Snap, AllegroServe, etc. Routing 
web frameworks allow you to literally host source files anywhere. For 
example, using Happstack I can say something like (forgive the Haskell 
code):

route =
   msum [ file "file.txt" $ serveFile "/home/someUsername/files/blah.wav" ]

As you can see, what was requested has absolutely nothing to do with 
what was actually served to the browser.

So, the only way you can begin to solve this issue is if you have direct 
access to the web server and know how it's routing and serving static 
content.
