Everyone knows that if you try to access a page that doesn't exist, the server will throw you back 404 page not Found, or if you mess up your rails code, you will get a 500 Application Error.

每个人都知道如果打开一个并不存在的页面，服务器会返回一个404错误页面。如果你的Rails程序出错了，会返回一个500应用程序内部错误的页面。

As a result, if someone comes across an error (for example, a 404 page Not Found, 403 Forbidden, or 500 Internal Server error), he will only see an ugly error code page.

因此，如果某人遇到一个错误(例如，404 Page Not Found、403 Forbidden或500 Internal Server Error等错误)，他将看到一个难看的错误代码页面。
