Putting PHP and Rails on the same server - php

Question

I am currently working on a website where the core of the website is in PHP. I now want to write a bunch of applications on top of that core, and was hoping to do it in Rails. I saw a couple things online where you could set single folders to be handled by PHP, (example: http://macdiggs.com/2007/06/29/using-php-inside-rails-structure-on-apache/) but I am hoping to do the opposite, have single folders that are handled by Rails, and then the rest is handled by PHP. For example, having ourwebsite.com/blog as a Rails app, but ourwebsite.com and ourwebsite.com/internal are all in PHP. What kind of Apache configurations would let this happen?
(As a bonus, my server is managed by Plesk, so I am concerned about making straight changes to the apache configuration. I have root access, so I can do it, but I am worried that Plesk might get mad)
EDIT: I should also mention, I am using Subdomains as part of my application, so I would really prefer to have something like ourwebsite.com/rails_app. If that is the only option, I can go that route, but I would prefer not to.

Answer 1

If you want the PHP app to be default application and only use Rails for a subdirectory, this Apache configuration should work for you:
DocumentRoot "/path/to/your/php/app/html"
ProxyPass /some_resource http://127.0.0.1:3000/some_resource
Note that your rails application would be running on port 3000 and you will need the ProxyPass Apache module installed.
