I don't think the shell would do that. It could be some canonicalization
happening in the client, or something in Apache. Hard to know offhand.

Yes and no. I suspect that you have a "foobar" in your document root. That
has been my experience when something like this happens.
The other thing is to ensure that your Location block doesn't have a
trailing slash. That seems to always act a bit weird.

No way. Lines like that are to handle broken clients. Since we know that the
client can be fixed, then that is the correct approach. The
redirect-carefully should never be used to allow/enable broken behavior.

Nope, cuz it shouldn't be in the docs :-)

It is totally fine if it wants to redirect non-GET requests. Roy can explain
the subtle differences between a URL that ends in a slash and one that
doesn't, but the simple fact is that the server should be able to do the
redirect, and the client should be able to handle it. A client that cannot
is considered broken (and deserves 10 lashes :-).
Ah. Here is a simple example. There is a resource on the server that refers
to a directory on the disk; the URL is http://example.com/dir/. If you GET
it, then you get the index.html and there is an HREF in there to
"page.html". If there was no slash on the end of the request URL, then
following the link takes to http://example.com/page.html. Thus, the server
does a redirect to ensure the slash is present, so that relative links take
you to the right place: http://example.com/dir/page.html.
If you ever attempt to refer to the resource, then you should use the URL
that refers to that resource. Whether it is a GET, a PROPFIND, or a COPY.
Thus, the redirection to ensure that you get the slash on the end.
