从非 www 重定向到 www

Question

我有两个网站 - 我为它们制作了相同的 htaccess 文件（当然每个都有不同的链接）。他们是一样的。我的目标是从非 www 重定向到 www。现在它适用于第一个网站。对于第二个，它也可以工作，但仅在 /index 上，其余页面不会重定向。知道问题可能是什么吗？我相信我检查过的htaccess没有错误，它们应该是完全一样的。

文件 - 它适用于 AAA，不适用于 BBB。 Htaccess 代码如下：

Answer 1

对于两个网站（AAA 和 BBB），请使用以下内容：

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(?!www\.) [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

这翻译为：

• 对于每个不以www. 开头的URI，将URI 重写为：

  http://www.[the-rest-of-the-domain][/the-rest-of-the-uri]
