我正在設定一個新的 Linux 伺服器。我想默默地重定向
www.domain.com/whatever到www.domain.com/flows/default/whatever
除非明確指定流程，例如
www.domain.com/flows/beta/whatever
在我的網域的 VirtualHost 條目中，我有以下內容：
LogLevel error rewrite:trace6
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,NC,R=301]
RewriteCond %{REQUEST_URI} !^/flows/ [NC]
RewriteRule ^ /flows/default%{REQUEST_URI} [NC]
</IfModule>
其中「domain.com」是我的實際網域 obv。
這也是我過去一直在使用的兩條規則，但是現在有些東西不起作用了。任何被第二條規則修改的 URL 都會顯示一個 404 頁面，其中包含以下訊息：
The requested URL /cgi-sys/ea-php70/index.php was not found on this server.
輸出日誌的中間是以下行：
init rewrite engine with requested uri /cgi-sys/ea-php70/index.php
我對一切的運作方式了解不夠，無法理解為什麼 CGI/PHP 會參與這個過程。這是完整的日誌：

所以官方問題是，為什麼我的重定向不起作用以及我需要做什麼來糾正它？
如果您需要任何其他信息，請告訴我。多謝你們。
更新
配置為 CentOS、cPanel、Apache 2.4、MPM Event、PHP-FPM、PHP 7、suEXEC。
好的，所以我添加了RewriteCond %{REQUEST_URI} !^/cgi-sys/ [NC]第二條規則只是為了讓它起作用，現在它就起作用了。如果有人有想法，我仍然想知道內部發生了什麼，僅供個人了解。
