Packrat parsing HTTP

Question

could somebody give me a start on how to parse the HTTP-protocol with scala 2.8 packrat-parsing?

I need to parse attached examplary HTTP Response into

• ResponseStatusCode:Int
• Headers:List[(String,String)]
• Body: String, Array[Byte], CharBuffer or whatever

Short examplary usage of a Packrat-Parser very much appreciated. Thanks!

There are abundant on-line resources about using Scala's combinator parser library.
