On servers where URLs map directly to filespecs, you can't have both /foo/bar
and /foo/bar/ unless the underlying filesystem differentiates between the two.
I'm not aware of any filesystems which simultaneously allow both /foo/bar and
/foo/bar/ since in most filesystems directories are simply a special form of a
file.
In the general case, however, URLs != filenames. You could easily have a
URL-to-file mapping layer which converts /foo/bar to /foo/bar.bork and
/foo/bar/ to /foo/bar/index.bork, in which case your two URLs /foo/bar and
/foo/bar/ could both peacefully coexist in the filesystem, even with a one-to-
one mapping. Since this is likely to confuse (or confound :-) users, it's
probably a good idea to help a user get to /foo/bar/ if they accidentally
arrive there via /foo/bar and /foo/bar doesn't exist while /foo/bar/ does
exist.

| (...) In this example, if /foo/bar doesn't exist the user should get what /foo/bar/ points to, one way or another. Not a page to help them get to it. Either redirect (current practice) or rewrite (possible option) /foo/bar to /foo/bar/. If you (...) (24 years ago, 13-Jun-00, to lugnet.admin.general)
