Here is the situation: I have a webserver (let's call it C1) that is running an apache/php server and it is port forwarded so that I can access it anywhere. However there is another computer within the webserver LAN that has a apache server too (let's call it C2). I cannot change the port forwarding nor I can change the apache server (a.k.a. install custom modules). My question is: is there a way to access C2 within a directory of C1? (e.g. going to www.website.org/random_dir will allow me to browse the root of C2 apache server.)

I am trying to change as little as possible of the config/other (e.g. activating modules etc.)

Is there a possible solution?

Thanks in advance.
