Apache ProxyPass无法加载资源

Question

我配置了apache proxypass，它正在工作，但未加载图像，javascript，CSS等...我想将proxypass传递到另一台服务器，而不是localhost。下面是我的配置。

see error image

<VirtualHost *:80>
    ServerName app.server.com
    DocumentRoot /var/www/html/subdomain

    RewriteEngine on
    ProxyRequests Off

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

    ProxyPass /apm http://192.168.1.102:9999/
    ProxyPassReverse /apm http://192.168.1.102:9999/

</virtualHost>
