How rails applications actually work? Let's say we have nginx + passenger + Ubuntu, so my questions are:

What is nginx actually doing?
How does it transfer requests to the rails app?
what is passenger responsible for?
And what is rack?
How actually rails app can work just on webrick without apache?

Please dont give me answers like "nginx processes the requests"; I need something more, or may be you know the source where I can read about this.
