title: How is URL delivered to the router in Cake?
body: <p>www.foo.com/blog/posts/view/12/12/2013</p>
  
  <p>There is no possible file corresponds to this request. So this URL needs to be parsed by some logic, or else you get a 404.</p>
  
  <p>Since there is no corresponding file, the response cannot be automated by the server. I was just wondering which part of Cake FIRST responds to a request like this. I understand simple page requests are first parsed and resolved by the router. But the URL cannot just magically get to the front door of the router, right? I really want to know what is going on behind the scene that brings the URL to the router.</p>
