I get a 301 if the directory "foo" exists; and a 404 if it does not.

Do you get something different?

If you request "/directory", and "directory" exists, then the filesystem
handler will issue a 301 to "/directory/", which I think is what you
are seeing.

As in: your request for "/foo" does not match any location{}, and so is
handled at server-level, which runs the filesystem handler and returns
200 if the file "foo" exists, 301 if the directory "foo" exists, and
404 otherwise.

Change your config to be

location /foo/ { return 200 "location /foo/\n"; }

and you will see when that location is used.

If your config has

location /foo {}

then a similar consideration applies, except the request "/foo" is now
handled in that location which, per the above configuration, uses the
filesystem handler.
