getResponseHeaders should return a list of values

[aagahi]

Headers could contains many values for same key (see Set-Cookie - http://en.wikipedia.org/wiki/Http_cookie)

As s suggestion here is a dummy impl:

def getResponseHeaders(conn: HttpURLConnection): Map[String, List[String]] = {
  // according to javadoc, there can be a headerField value where the HeaderFieldKey is null
  // at the 0th row in some implementations.  In that case it's the http status line
  val map = Stream.from(0).map(i => i -> conn.getHeaderField(i)).takeWhile(_._2 != null).map{ case (i, value) =>
    Option(conn.getHeaderFieldKey(i)).getOrElse("Status") -> value
  }.toList.groupBy(_._1)
  for ( (k,v) <- map ) yield  k -> v.map(_._2)
}
