Play provides you a Map[String, Seq[String]] (aliased as UrlFormEncoded) in request body for urlFormEncoded requests. It's generally a lot more convenient to work on Map[Path, Seq[String]] to define Rules. This object contains methods used to convert Map[String, Seq[String]] <-> Map[Path, Seq[String]]

Note
We use the alias UrlFormEncoded, which is just a Map[String, Seq[String]]
