I have two servers, one a development server that is accessible internally on our company's local network and the other a public-facing web server. The development server hosts several tools that we use to manage our projects internally but now we need to access them externally too whilst maintaining security.
I have set up mod_proxy on the external server using the ProxyPass and ProxyPassReverse directives to map external requests to the internal server. I have also set up authentication on these external virtual hosts to provide security for outside access. I also need to use SSL for external access but would ideally prefer to keep the internal tools accessible by plain HTTP for people within the intranet.
Is it possible to achieve this behaviour and if so what directives and Apache modules should I be using and on which servers do they need to be setup?
