1.11 +/*
1.12 + A pushed stream is put into a memory buffer (The SpdyPushTransactionBuffer)
1.13 + and spooled there until a GET is made that can be matched up with it. At
1.14 + that time we have two spdy streams - the GET (aka the sink) and the PUSH
1.15 + (aka the source). Data is copied between those two streams for the lifetime
1.16 + of the transaction. This is true even if the transaction buffer is empty,
1.17 + partly complete, or totally loaded at the time the GET correspondence is made.
1.18 +
1.19 + correspondence is done through a hash table of the full url, the spdy session,
1.20 + and the load group. The load group is implicit because that's where the
1.21 + hash is stored, the other items comprise the hash key.
1.22 +
1.23 + Pushed streams are subject to aggressive flow control before they are matched
1.24 + with a GET at which point flow control is effectively disabled to match the
1.25 + client pull behavior.
