Take 2 with a modified Quixote demo has:
/         -- (dynamic) no errors
/apache/  -- (static) usual errors
/foo      -- (dynamic) no errors
/bar      -- (dynamic with extra headers) no errors
/baz      -- (static, same content as bar)  Internal Server Error often


    _q_exports = ["", "simple", "plain", "error", "publish_error", "css",
                  "dumpreq", "extras", ("favicon.ico", "favicon_ico"),
                  "apache", "foo", "bar", "baz"]


    apache = StaticDirectory("/var/www/localhost/htdocs/",
        follow_symlinks=True, index_filenames=["index.html"],
        list_directory=True)

    def foo(self):
        return "Foo!"

    def bar(self):
        r = get_response()
        r.set_header('X-Test-1', 'a'*40)
        r.set_header('X-Test-2', 'a'*40)
        r.set_header('X-Test-3', 'a'*40)
        return "Bar!"
