In order to do other things (such as logging) successfully, there must be some chain from an HttpSM instance to the SpdyClientSession. Where should this link be? It seems simplest and most comprehensible to me to chain it via the client session. It also makes it nicely hierarchial, that is a protocol stack. Here is a picture of what I think is a reasonable data structure. Note the only change between what is there now and this diagram is the addition of parent links from the HttpClientSession.
