Helpers and functionality in sinatra, worth discussing if we should include similar:

 * Helper for accessing the session?
   - session
     * What does rack::session give you? is it any good?

 * Helper for setting content type
   - content_type :json
     * this is equiv to headers(:content_type =>  ... ), see above
     ** kind of except this is mime-type intelligent

 * Send a file as a response
   send_file "some/file.txt"
   yes!

 * Support for cache_control, expires, last_modified, etag
   cache_control :public, :must_revalidate, :max_age => 60
   expires 500, :public, :must_revalidate
   etag(value, options = {})
   last_modified(time)
   see above!


 * mime-type provides?
 yes!
 * user_agent filtering helpers?
 yes !
