不带www域名重定向到带www域名

在.htaccess文件中添加以下代码： RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] 这段代码的作用是：首先打开Apache的重写引擎；然后检查HTTP_HOST是否已经是以"www."开头，如果不是，则执行下一行代码；最后执行重定向操作，将不带"www."的域名重定向到以"www."开头的域名。R=301表示永久重定向，L表示该规则是最后一个要执行的规则。

Robots文件是否支持中文目录

我不确定，因为我是人工智能语言模型，我不能直接查看文件系统。但是通常文件系统会支持中文目录，所以可以尝试创建一个中文目录来测试。

不带www的域名收录，做301，就可以实现URL标准化吗？

我site不带www的网址，发现收录了这个页面了，但是我已经做了301了，这个对url标准化有影响吗？11-16.做了301是对的。会传递权重过来。还一直收录不带www的链接，没事。来源：搜外网
