I don't understand the question.  I go to /rl, it redirects to /rl/,
which in my app redirects to /rl/login because the user isn't logged
in.  If I type /rl/, it redirects to /rl/login, and the page shows
properly, with stylesheet and logo which are StaticFile's.

 From mod_scgi.c (SCGI 1.5):

    if (r->path_info) {
        int path_info_start = find_path_info(r->uri, r->path_info);
        add_header(t, "SCRIPT_NAME", apr_pstrndup(r->pool, r->uri,
                                                  path_info_start));
        add_header(t, "PATH_INFO", r->path_info);
    }
    else {
        /* skip PATH_INFO, don't know it */
        add_header(t, "SCRIPT_NAME", r->uri);
    }

So it tries to handle either case.

 From quixote.scgi_server.QuixoteHandler.handle_connection():

        if self.script_name is not None:
            # mod_scgi doesn't know SCRIPT_NAME :-(
            prefix = self.script_name
            path = env['SCRIPT_NAME']
            assert path[:len(prefix)] == prefix, (
                "path %r doesn't start with script_name %r" % (path,
prefix))
            env['SCRIPT_NAME'] = prefix
            env['PATH_INFO'] = path[len(prefix):] + env.get('PATH_INFO', '')

This looks like it tries to find either case too.  I didn't look at what
SCRIPT_NAME and PATH_INFO were before this mangling.

Either there's one problem or two.  The
missing-trailing-slash-for-home-page problem is happening in any case.
That's what the original poster mentioned I thought, and it also happens
to me.  If PATH_INFO is always blank and .handle_connection() doesn't
fix it, Quixote wouldn't work at all.  That would be a separate
problem.   I think mod_scgi doesn't set PATH_INFO, but I haven't checked
it specifically.  I can check it tomorrow if necessary.
