Yo dawg, I heard you like… Purely theoretical (obviously) case: you have existing php app and some legacy rails code that you refreshed a little bit and now someone asks you one simple question - why can’t you just put that code into that code and run it as one app? Sometimes you can reason, sometimes not. But let’s do it - I mean seriously - let’s create some kind of hybrid that will work transparently and silently for the user. Unleash your imagination and get ready for breaking every programming paradigm; treat it like a sport and get ready :). Let’s ever get a little bit further, let’s create one rails app that will distribute its content for two different domains. Where do we start?
