Provide a mechanism for filtering requests before and after

[lantunes]

The server should provide a mechanism for performing actions before and after a particular kind of request. Below is a rough example:

server.before(Method.GET, "/protected/*")
    .with(new HttpRequestHandler() {
         public void handle(HttpRequest request, HttpResponse response) {                    
             logger.log("a request was made to " + request.getPath());
            }
    });

A corresponding method would exist for after().
