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