Apache2 将 /example 指向另一个本地 ip 网络服务器

Question

我有一个在 192.168.1.2 上运行的 apache2 服务器，可以使用 publicip/ 从外部访问。

我想要做的是将 publicip/example1 重定向到另一个本地 ip（比如说 192.168.1.3），并将 publicip/example2 重定向到另一个 ip（192.168.1.4），...

我尝试按照此处的说明进行操作：https://stackoverflow.com/questions/21441227/apache-using-reverse-proxy-and-run-local-website

因此我创建了一个如下所示的 site.conf：

<VirtualHost *:80>

    ServerName mysite.com
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/mysite.com

    <Directory /var/www/html/mysite.com>
            require all granted
            AllowOverride All
    </Directory>

    <Location /example1 >
            ProxyPass http://192.168.1.3:80/
            ProxyPassReverse http://192.168.1.3:80/
    </Location>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

使用此配置，我可以以 root 身份访问 mysite.com，但是当我尝试连接 mysite.com/example1 时，它不起作用并出现此错误：

Internal Server Error

Please contact the server administrator at webmaster@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

Apache 错误日志显示：

请问我做错了什么？

谢谢！
