Redirect Joomla网站正在获得303重定向循环
我的网站有时会在主页上出现303重定向循环。这给了我一个错误，当我试图查看该网站的网页有一个重定向循环，但大多数时间是罚款。但是，303重定向看起来不适合搜索引擎优化。我正在使用Zo2框架运行Joomla3.2.3。我使用了firefox live http headers工具，它显示了以下内容：Redirect Joomla网站正在获得303重定向循环,redirect,joomla,Redirect,Joomla,我的网站有时会在主页上出现303重定向循环。这给了我一个错误，当我试图查看该网站的网页有一个重定向循环，但大多数时间是罚款。但是，303重定向看起来不适合搜索引擎优化。我正在使用Zo2框架运行Joomla3.2.3。我使用了firefox live http headers工具，它显示了以下内容： HTTP/1.1 303 See other Date: Sat, 19 Apr 2014 06:42:44 GMT Server: Apache mod_fcgid/2.3.10-dev X-Pow

我仍然需要一些帮助。303不一定是一个错误，根据插件的用途可能是期望的行为。我的猜测是this.href没有正确填充正确的303 url。你能发布整个JS文件吗？这样我们就可以看到这个.href被分配到哪里了？这是整个site.megamenu.JS文件。我把它加到原来的问题上。你说303不是一个错误，但它不会伤害我的网站与谷歌？澄清一下，303本身并不是一个错误。它是HTML 1.1规范的合法响应代码部分，您可以在此处阅读：。然而，您遇到的循环错误似乎是303的一个不正确的应用程序，并且很可能会导致Google出现问题。当我有时间的时候，我会查看发布的JS，看看我是否能找出问题所在。我做了更多的研究，并在第一篇文章中添加了一些额外的信息。我不知道这是否有用。
