Rails page life cycle, good write ups/tutorials on this?

I开发者_StackOverflow社区 want to read about, in detail, a rails page life cycle, along with the initial page request that loads the website.

I have no idea what's going on here :)

There's not much to tell -- a request gets routed to a Controller, and the Controller responds by either rendering a page or redirecting the request to another page.

Then there's the Rack middleware stack. You can see the stack by running rake middleware. Every request works its way down the chain before hitting the Controller, and then goes back up the way it came. A lot of framework stuff is actually running on top the application as middleware.

Tekpub has a pretty good screencast on Rack middleware for free. (You have to create a free account first -- OpenID is supported)

O'Reilly has a pretty good introduction chapter to Rails available here.
