Sure is. We do it with apache 2.4.25 and we also rewrite to https at the same time. RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} SSLProxyEngine On RequestHeader set Front-End-Https "On" ProxyPreserveHost On ProxyRequests Off ServerName ispcp.domain.name ServerAlias controlpanel.ispcp.domain.name ProxyPass / https://1.2.3.4:8080/ ProxyPassReverse / https://1.2.3.4:8080/ <Proxy *> Order deny,allow Allow from all </Proxy>
Sorry, yes you can. You can use the Options tab under the domain to enter the details to be added to the config, which is how we add the above settings in apache.
Do you want to reverse proxy internal applications on websites hosted on ispconfig (cwispy already answered that) OR you want to reverse proxy the ispconfig application it self ?
