 Bidirectional streams allow for data to be sent in both directions.
 
 Streams are identified within a connection by a numeric value, referred to as

 The least significant bit (0x1) of the stream ID identifies the initiator of the
 stream.  Client-initiated streams have even-numbered stream IDs (with the bit
