| // 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. |
