我需要使用301重定向将网站从example.net重定向到www.example.net。
我正在为我的网站使用All In One WP安全性和防火墙，它会自动在.htaccess文件中添加其他代码。重定向无法正常工作，我认为这是由该额外的代码引起的。我在浏览器中看到的错误是：
尝试打开www.example.net时发生太多重定向。
一站式WP安全性和防火墙会产生这样的错误吗？
我的301代码：
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^example.net [NC]
RewriteRule ^(.*)$ www.example.net/$1 [L,R=301,NC]
多合一代码：

最佳答案
问题出在
RewriteRule ^(.*)$ www.example.net/$1 [L,R=301,NC]
www.example.net被视为相对路径，而不是其他域。这就是为什么将URL
http://example.net/some/path重写为http://example.net/www.example.net/some/path，然后再次将其重写为http://example.net/www.example.net/www.example.net/some/path的原因。如果要从域
example.net重写为域www.example.net，则还必须添加协议（http），例如RewriteRule ^(.*)$ http://www.example.net/$1 [L,R=301,NC]
重定向域批发的另一种方法是使用
Redirect指令Redirect / http://www.example.net
RewriteCond %{HTTP_HOST} !^www\.(.*)$ [NC]
RewriteRule ^(.*)$ %{HTTP_HOST}/$1 [L,R=301,NC]
使用
%{HTTP_HOST}具有相同的效果，因为它不包含方案，即http或https。此外，您从%{HTTP_HOST}重写为%{HTTP_HOST}，这没有改变。要解决此问题，您必须在替换前面加上
www.和一个方案，即http或https。此处不需要标记NC，因为无论如何您都将查找任何字符.*。所以规则应该看起来像RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R]
最后，切勿使用
R=301进行测试！有关详细信息，请参见此答案Tips for debugging .htaccess rewrite rules。
