-- | Iteratees for header parsing.
module Network.IHttp.Header

-- | Get the next header from the <tt>netLinesEmpty</tt>-splitted stream.

--   an iteratee error, if the next lines are not a valid HTTP header or
--   the stream ends prematurely. If the next line is an empty line, this
--   iteratee returns <a>Nothing</a>.
httpHeader :: Monad m => Int -> Iteratee ByteString m (Maybe (ByteString, ByteString))

-- | Get the headers of an HTTP request from a
--   <tt>netLinesEmpty</tt>-splitted byte stream. The first <a>Int</a>
--   specifies the maximum length of individual headers. The second
--   <a>Int</a> specifies the maximum number of headers. This iteratee
--   throws an iteratee error on invalid input, of if the stream ends

--   
--   Excess data is truncated safely in constant space.

response :: Monad m => Int -> Int -> Iteratee ByteString m Response

-- | Get the next response line form <tt>netLinesEmpty</tt>-splitted
