Example

  condition(
    function (req, res) { // condition
      if (~req.url.indexOf('json')) {
        return true
      }
    },
    function (req, res, next) { // middleware which is choosen on condition == true
      res.setHeader('Content', 'application/json')
      res.end('{ "text": "as json" }\n')
    },
    function (req, res, next) { // middleware which is choosen on condition == false
      res.end('just text\n')
