Re: SPDY/H2 and Session hooks

[Alan M. Carroll]

My view is the SSN hooks should be called on the user agent connect / 
disconnect, the base client session object. That would mean that for an Http/2 
session, the SSN hook is called only when the user agent initially connects for 
HTTP/2 and once when the HTTP/2 connect is terminated, and *not* for each 
transaction. Since SPDY and HTTP/2 only do one transaction per stream/channel 
the SSN hooks aren't very useful.
