I've got a Linux web server that responds to http requests from the web through a simple port-forward. The domain name points to my IP and the requests are forwarded to apache. Apache checks the domain name and serves the correct website.
Now I want to include another webpage, but this can only be served from a Windows machine. I don't have expensive equipment that can do different forwards based on the URL that is requested, so I was thinking to maybe use an html page with an IFRAME, pulling the data from Windows through my Linux box. Not sure if this is the preferred way to do this. (e.g. https://stackoverflow.com/questions/3224648/include-a-website-in-php-file)
There is no heavy load on the servers and the code on both servers is completely under my control, so I have no worries about code security.
I'm just thinking now that maybe there's a better way to tackle this problem, I just don't know what's bests practise.
