据我所知，我没有以任何形式或形式引用 favicon.ico，但我对 rails 服务器（处于开发模式）的每个请求都以以下内容结尾：

Started GET "/assets/ico/favicon.ico" for 127.0.0.1 at 2012-06-12 20:18:02 -0700
Served asset /ico/favicon.ico - 404 Not Found (3ms)

这是与 webrick 相关的问题，还是我需要更改一些配置选项或什么？

编辑：我将 favicon.ico 放在 app/assets/ico/favicon.ico、lib/assets/ico/favicon.ico 和 public/favicon.ico 中。favicon 徽标甚至出现在我的浏览器中，但 rails 服务器仍然在日志中显示 404。有什么建议么？

这不是 Rails——Web 浏览器会自动请求它。

浏览器会自动查找您网站的图标（您在地址栏和书签中的 URL 旁边看到的图标）。最简单的方法是创建一个 favicon 并将其保存到 /assets/ico/favicon.ico。
