Apache ProxyPass and ReverseProxy to a SSL HTTPS configured domain.

Posted on March 4, 2015

Hi,

I hope you can help with this because I am a little bit confused.

I’m running apache 2.2 httpd and want to communicate using ProxyPass and ProxyPassReverse to a secured server which is also HTTPS SSL.

Sample architecture:

Outside world ==> https ssl Apache 2.2 httpd (localhost) ==> Secured server Https ssl (domain.com) I am the middle man here.

What exactly do I need from them (domain.com) in order for me to configure Apache 2.2 httpd-ssl.conf properly? Do I only need their public key? I don’t think I also need their certificate, otherwise I can generate their private key. I don’t think that’s handy…and insecured.

This is my current configuration for when the outside world visit the middle man apache server.

After doing some digging on this particular need I was able to find this thread on the Ubuntu forums which outlines the same problem and provides a solution with an example configuration file known to be working.

Hi @PokerFace,

It’s indeed a strange configuration, usually, the application you are Proxy redirected is on your Droplet rather than outside of it. If it’s possible I’ll suggest such one.

As for a solution, I see you’ve found one and it’s indeed working, I’ve tested it out. Having said that, as said earlier, I’ll recommend to avoid such scenarios wherever possible.
