coroutine decorator communicates with the generator via the yield expressions, and with the coroutine’s caller by returning a Future. Here is a simplified version of the coroutine decorator’s inner loop: # def initialize(self, db): self.db = db def get(self, story_id): self.write("this is story %s" % story_id) app = Application([ url(r"/", MainHandler), url(r"/story/([0-9]+)" Application([ url(r"/app", tornado.web.RedirectHandler, dict(url="http://itunes.apple.com/my-app-id")), ]) RedirectHandler also supports regular expression substitutions. The following rule redirects
