Those headers are hop-headers and only make sense for one http-transport
level.See rfc2616 §13.5.1 for more information, but please note that the
errata has fixed some typos so depending on what rfc you read it may or
may not show you the list rabbit has (which as far as I know follows the
latest errata, but it was some time since I checked last).
