I'm running a small server hosting 2 websites with Apache2 on Ubuntu 12.10.
The server has 2 network cards each connected to a different router. Each router has it's own internet connection, 1 personal and 1 business. I'd like to force webserver1 to use the personal internet connection and webserver2 to use the business internet connection for out going requests. I don't want webserver2 using my personal internet connection. Apache2 VirtualHosts for each webserver are set to listen on 2 different domains but how do I know that the outbound requests made by either server is using the proper network connection?
