You are right.
The reference to http in 3920 might be slightly confusing, but the
intent is that all stanza's from server to the remote server goes only
over the outbound connection.
And server will recieve stanza's only over the inbound socket - after
the session has been established. That is, you could have stanza's
exchanged both ways over an s2s stream before session establishment is
