Re: SCGI + Quixote, Location / ?

I should have piped up earlier, but this behavior also occurs with
mod_python.  I can't speak for mod_scgi's SCRIPT_NAME and PATH_INFO
behavior, but as of Quixote 2.0 (haven't tried 2.1 yet, though I need to
get rolling on the Fedora Extras packages...) the "abort on an empty
PATH_INFO" behavior essentially means that Quixote will append a
trailing slash onto any directory except the root, leading to situtions
where "http://example.com/one/two/three" redirects with the trailing
slash but "http://example.com/one/two" does not (unless the developer
jumps through some hoops to work around this behavior in the publisher).

I'm not sure what the correct behavior is, but I think consistency is
probably the best policy. Possibly changing Publisher.try_publish to the
following would work:

The above would even stand a chance of working where SCRIPT_NAME is a
directory and PATH_INFO doesn't start with a slash without trying to
guess what PATH_INFO and SCRIPT_NAME should have been.
