Scott Mitchell 0a47c590fe HttpHeaders valuesIterator and contains improvements ... Motivation: In order to determine if a header contains a value we currently rely upon getAll(..) and regular expressions. This operation is commonly used during the encode and decode stage to determine the transfer encoding (e.g. HttpUtil#isTransferEncodingChunked). This operation requires an intermediate collection and possibly regular expressions for the CombinedHttpHeaders use case which can be expensive. Modifications: - Add a valuesIterator to HttpHeaders and specializations of this method for DefaultHttpHeaders, ReadOnlyHttpHeaders, and CombinedHttpHeaders. Result: Less intermediate collections and allocation overhead when determining if HttpHeaders contains a name/value pair.		2017-11-20 08:34:06 -08:00
