  // the URL. Other times, we will actually fetch |url| to examine its
  // content-type and/or sniff it to determine the correct handler.

  // When the caller receives the result, it should connect to the application
  // at |handler_url| and navigate it to |view_url|.

  // redirects. Applications should navigate to view_url, not |url| or
  // response->url.

  // Note: |response| can be NULL in the case where a request was not needed to
  // determine the correct handler.
