使用 mod_proxy[_html] 时出现许多 404 URL

我想做的事

让所有http://cloud.example.com/出现为http://webmail.example.com/cloud/

我是如何尝试的

<VirtualHost  *:80>

  ServerName webmail.example.com
  DocumentRoot /var/www/roundcubemail-1.1.4
  Loglevel debug
  ErrorLog /var/log/apache2/roundcube.error
  # %t  : Time 
  # %a  : client ip 
  # %f  : filename
  # %T  : processing time 
  # %s  : status
  # %>s : Final status
  LogFormat "%t %a %{Referer}i -> %U%q, matches %f, %s>%>s(served in %{ms}T µs)" custom
  # was "combined"
  CustomLog /var/log/apache2/roundcube.access custom     

  ProxyPass  "/cloud/" "http://cloud.example.com/"
  ProxyPassReverse "/cloud/" "http://cloud.example.com/"

  # The ProxyRequests directive should usually be set off when using ProxyPass.
  # src:https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass
  ProxyRequests off

  # https://httpd.apache.org/docs/current/mod/mod_proxy.html#proxypreservehost  
  # This option should normally be turned Off.
  ProxyPreserveHost off

</VirtualHost>

日志的第一行显示请求“/cloud/”路径成功从代理网站检索资源，但所有后续资源都不是从云服务器获取的，而是从网络邮件服务器本身获取的。

我该如何处理这个问题？

我已启用 proxy_html。

根据@HBruijn的建议，我添加了

  ProxyPass "/core/" "http://cloud.algerian-radio.dz/core/"
  ProxyPassReverse "/core/" "http://cloud.algerian-radio.dz/core/"

但随后服务器收到了 /index.php/apps/files/ 的请求，因此我也添加了它

  ProxyPass  "/index.php/apps/files/" "http://cloud.algerian-radio.dz/apps/file\
s/"
  ProxyPassReverse "/index.php/apps/files/" "http://cloud.algerian-radio.dz/app\
s/files/"

消除了所有 404 错误，但是仍然无法让 owncloud 正常工作。

http://webmail.example.com/cloud重定向至http://webmail.example.com/index.php/apps/files/显示这个错误：

Fatal error: Class 'OCP\User' not found in /usr/local/nginx/html/owncloud/apps/files/index.php on line 33

编辑：固定的 ！，owncloud 需要进行一些额外的配置，即受信任的代理和覆盖网页根目录。
