龙卷风请求处理程序微调

Question

我有一个404请求处理程序来处理像http://host:port/mycompany这样的情况。这是代码。

class Application(tornado.web.Application):
    def __init__(self):
        handlers = [
            (r"/", HomeHandler),
            (r"/mycompany", myCompanyHandler),
        ]
        super(Application, self).__init__(handlers,     default_handler_class=my404Handler)

class myBaseHandler(tornado.web.RequestHandler):
        def write_error(self, status_code, **kwargs):
                if status_code == 404:
                        self.render("404.html")
                else:
                        self.render("genericerror.html")

class my404Handler(myBaseHandler):
    def prepare(self):
            raise tornado.web.HTTPError(404)

class HomeHandler(myBaseHandler):
    def get(self):
            self.render("home.html")

class myCompanyHandler(myBaseHandler):
etc
etc
etc

我想在用户输入http://host:port/mycompany/时显示404页面（注意结尾处的正斜杠）。我错过了什么？
