| 8 /* | |
| 9 A pushed stream is put into a memory buffer (The SpdyPushTransactionBuffer) | |
| 10 and spooled there until a GET is made that can be matched up with it. At | |
| 11 that time we have two spdy streams - the GET (aka the sink) and the PUSH | |
| 12 (aka the source). Data is copied between those two streams for the lifetime | |
| 13 of the transaction. This is true even if the transaction buffer is empty, | |
| 14 partly complete, or totally loaded at the time the GET correspondence is made. | |
| 15 | |
| 16 correspondence is done through a hash table of the full url, the spdy session, | |
| 17 and the load group. The load group is implicit because that's where the | |
| 18 hash is stored, the other items comprise the hash key. | |
| 19 | |
| 20 Pushed streams are subject to aggressive flow control before they are matched | |
| 21 with a GET at which point flow control is effectively disabled to match the | |
| 22 client pull behavior. | |
