在Rails 3.2.3服务器中我得到错误304未修改（5ms）

我现在是ruby和rails的新手几个月了。我参加了ruby和铁轨课程，这让我可以创建一个餐馆博客网站。好吧，我最近开始改造网站，为我的朋友。所以它只是改变图片，措辞等方面的一些东西。当我完全创建另一个博客时，我做了一个注册登录页面，他们需要创建一个登录，以创建和发表评论等。一切似乎当我为本地主机服务器运行rails时工作正常，但是当我为站点创建登录以确保一切正常时。它不允许我创建登录，并且我在rails服务器中不断收到错误。见下文！我搜索和搜索，似乎无法找到解决方案。我唯一真正改变的是一些图片和一些措辞。我没有搞乱编码登录，创建登录代码等。任何帮助都会很好，我将继续搜索。在此之前我得到了一个内容长度错误，所以我关注了这个网站http://theresa.multimediatechnology.at/webrick-warnings-in-ruby-1-9-3/ 。这似乎解决了这个问题，但现在我得到了以下内容。谢谢！

HTTP状态代码不表示错误。它只是意味着资产文件（图像，css，javascript）不需要再次传输，因为浏览器已经缓存了最新版本。

请参阅HTTP 3xx状态代码
