根路径的预渲染重定向不起作用

Question

我正在配置我的apache服务器来处理prerender的中间件，除了根路径之外，它实际上运行良好。

当我尝试抓取 www.example.com?_escaped_fragment _ 时，会返回 www.example.com / ，但未找到预渲染中间件。

像www.example.com/foo?_escaped_fragment_这样的其他网页可以正常使用。

这是我的apache配置：

<VirtualHost *:443>
    ServerAdmin ***
    ServerName example.com
            ServerAlias www.example.com

    SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

    DocumentRoot /var/www/example/current/web

    LogLevel warn

    <Directory /var/www/example/current/web>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>

    DirectoryIndex app.php

    ErrorDocument 503 /maintenance.html
