Simple Unfiltered example for providing OPTIONS, HEAD, and conditional GET

unfiltered-simple-caching.scala

class RootPlan extends Plan {
  val logger = Logger(classOf[RootPlan])
  val creationDate = new java.util.Date 
  val eTag = hashCode.toString

  val Head = Ok ~> Vary("Accept-Charset", "Accept-Encoding", "Accept-Language", "Accept")

  val Caching = 
    CacheControl("max-age=3600") ~> 
    LastModified(DateUtils.formatDate(creationDate)) ~> 
    ETag(eTag) 

  def intent = {
    case OPTIONS(_) => Ok ~> Allow("GET", "HEAD", "OPTIONS")

    case HEAD(Path(Seg(Nil))) => {
      logger.debug("HEAD /")
      Head
    }

    case req @ GET(Path(Seg(Nil))) => {
      logger.debug("GET /")
      val cached = 
        req match {
          case IfNoneMatch(xs) => xs contains eTag
          case IfModifiedSince(xs) => {
            val sinceDate = DateUtils.parseDate(xs mkString ", ")
            ! creationDate.after(sinceDate)
          }
          case _ => false
      }
      if (cached)
        Head ~> Caching ~> NotModified
      else
        Head ~> Caching ~> ResponseString(
          "To register: " +
          "curl -X PUT -d 'user[password]=pass' -d 'user[email]=you@host' -d 'user[full_name]=Your%20Name' -v http://localhost:8080/users/you")
    }
  }
}
