 // HttpStream provides an abstraction for a basic http streams, SPDY, and QUIC.
 // The HttpStream subtype is expected to manage the underlying transport
 // appropriately.  For example, a basic http stream will return the transport
 // socket to the pool for reuse.  SPDY streams on the other hand leave the
 // transport socket management to the SpdySession.
