在Rails 3.2.3服务器中我得到错误304未修改（5ms）

Question

我是新手到Ruby和Rails现在几个月。我为Ruby和Rails拿了一个课程，让我创建一家餐馆博客网站。好吧，我最近开始修改网站为我的朋友制作。所以它只是改变图片周围的一些东西，措辞等。当我完全创建另一个博客时，我创建了一个注册登录页面，他们需要创建登录，以便创建和发布评论等。一切似乎当我为本地主机服务器运行Rails S但是当我开始为网站创建登录时，请重新工作以确保所有内容正常工作。它不允许我创建登录，我继续在rails服务器中收到错误。见下文！我已经搜索和搜查，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。我没有用日志编码弄乱，创建登录代码等。任何帮助都将在平均时间继续搜索。在此之前我得到了一个内容长度的错误，所以我遵循这个网站 http://theresa.multimediatechnology.at/webrick-warnings-in-ruby-1-9-3/ 。这似乎可以解决这个问题，但现在我得到了下面的问题。谢谢！

Answer 1

HTTP状态代码不表示错误。它只是表示资产文件（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。

看 http 3xx状态代码
