I currently have a Sub Domain Proxies and Sub Folder Proxies working as seperate virtual hosts.

I want to minimise/simplify the code by combining.

My end game is to have Subdomains pointing to different Physical/Virtual Servers, while use subfolders to access different services in that server.

For Example:

www.example.com = Server 0 Apache www.example.com/webmin = Server 0 Webmin server1.example.com = Server 1 Apache server1.example.com/webmin = Server 1 Webmin server1.example.com/ad = Server 1 Active Directory UI server2.example.com = Server 2 Apache server2.example.com/webmin = Server 2 Webmin server2.example.com/ad = Server 2 Active Directory UI

I have the following working thou as separate VirtualHosts:

#NAS as nas.example.com ProxyPass / http://10.0.28.1:5000/ ProxyPassReverse / http://10.0.28.1:5000/ #Webmin as nas.example.com/webmin ProxyPass /webmin/ http://10.0.28.1:10000/ ProxyPassReverse /webmin/ http://10.0.28.1:10000/

My guess is the first entry is overriding the second as the first is /. I just can't seem to nut out how to override and make both ReverseProxies work within the same

  • ProxyPass directives are processed in order of the first match, simply list the one to the root / last rather than before /webmin/ if that is your problem. - But Apache httpd can easily handle 100’s if not more VirtualHost entries and you can use the Include directive to load a common section into all VirtualHost entries, so I am not quite clear what you want to simplify in your config.

  • I thought I tried changing the order, but will try again. I wanted to simplify for readability. I was thinking of using macros later too. I was just hoping to have a single virtual host setup per server keeping all its settings together. Commented Dec 22, 2017 at 7:05

Just tried reordering and it's still not working.

<VirtualHost *:443> # NAS ServerName nas.example.com ServerAdmin [email protected] DocumentRoot /mnt/WWW ProxyPass /webmin/ http://10.0.27.1:10000/ ProxyPassReverse /webmin/ http://10.0.27.1:10000/ ProxyPass / http://10.0.27.1:5000/ ProxyPassReverse / http://10.0.27.1:5000/ # SSL Certificates SSLEngine on SSLCertificateFile /root/ssl/example.com.crt SSLCertificateKeyFile /root/ssl/private.key SSLCACertificateFile /root/ssl/intermediateCA.crt # Error Logs ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>

The above is a reverse proxy to another server (the NAS). nas.example.com should be the NAS's default GUI while nas.example.com/webmin should point to Webmin on the same server (NAS). What is happening thou is /webmin returns a page from the NAS GUI saying the page cannot be found.

  • Update: I got it working. Changing /webmin/ to /webmin fixed it. But am having issues with the redirect. A page under the subfolder to any server (not just webmin) will try to get CSS, JS, IMG etc from the parent domain. Looking in the source shows nas.example.com/style.css when it should be nas.example.com/webmin/style.css I need to work out how to force the subfolder to be the parent of the reverse proxy.

  • That's usually a configuration issue on the application server. Commented Dec 22, 2017 at 7:39
  • serverfault.com/a/561897/37681 and the answer below mine for some thoughts on that Commented Dec 22, 2017 at 8:23
  • Will not work because Webmin server uses addresses starting with / that are related to the root of the Webmin server. We must rewrites urls, js, css in the pages served by the Webmin server. Commented Nov 6, 2023 at 12:24
