htaccess mod rewrite 以添加 www 重定向回根目录答案

【问题标题】：htaccess mod rewrite to add in www redirects back to the roothtaccess mod rewrite 以添加 www 重定向回根目录
【发布时间】：2016-10-19 03:42:17
【问题描述】：

我已添加：

RewriteEngine On
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301]

到我的 .htaccess 文件，所以如果 url 没有 www 在它添加它。但是，如果有人直接访问了一个没有 www 的页面，它会重定向回根目录吗？

例如，如果有人转到https://example.net/catagory 或http://example.com/catagory，它会重定向到https://www.example.net

谁能说明为什么会发生这种情况？

当不包含 www 时，我希望示例重定向到 https://www.example.net/catagory 而不是回到根目录。

【问题讨论】：

大概这是在 Magento 自己的 -d, -f, -l URL router 之前的根 .htaccess 中？
@CD001 我已经在上面添加了我的 htaccess 文件，你有什么不正确的吗？
见## never rewrite for existing files, directories and links这一行——该块开始了 Magento 自己的 URL 重写系统，你需要将你的移动到上面，否则 Magento 重定向将在你有机会之前得到信息。跨度>
工作得很好，谢谢！
顺便说一句 - Magento 的补丁系统似乎使用根 .htaccess 文件作为一种完整性检查或其他东西；自定义该文件将导致修补程序失败（尽管它说它成功了，但它只是进行了试运行，实际上没有更改任何文件，也没有应用修补程序）。您需要保留一份原版 .htaccess 文件的副本，以便在安装补丁时使用……至少在社区版中是这样。
