Sure.  But it's only in the most trivial of situations that URLs map in 
any trivial way to file names.

Well, I certainly could write an HTTP server on Linux which treated 
routes in a case-insensitive way.  For example, if I do a GET on 
http://en.wikipedia.org/wiki/hypertext, I get redirected to 
http://en.wikipedia.org/wiki/Hypertext.  On the other hand, 
http://en.wikipedia.org/WIKI/Hypertext gets me a 404.  It's entirely up 
to the server to do whatever makes sense for that application.

Hosts don't decide anything.  Applications running on those hosts decide 
things.  Without knowing the application, it's impossible to say if this 
is the right thing to do or not.

For example, it's good practice that if a URL ever worked in the past, 
you should keep that URL working, even if it becomes "obsolete".  You 
might want to silently return some other page, or redirect the user to 
some other URL.  This keeps bookmarks, existing links, cached search 
results, etc, from going stale.

To use the wikipedia example again, there are lots of redirect entries, 
for other (perhaps incorrect) spellings, and so forth.  For example, 
http://en.wikipedia.org/w/index.php?title=Taboule&redirect=no
