Re: [Quickfix-users] Session State

[<or...@qu...>]

Good question.

At first they may appear identical, but they are really quite different.

Think of onLogon and onLogout as confirmations.  

onLogon says that both sides have sent and confirmed logon messages.  We
have established a valid session and we are all ready to go.  It means
you are good to go.

No, the onMessage call for a Logon is the callback for the Logon
message, which could be the ingoing OR outgoing logout, depending on
which callback it arrived from.  This lets you view the internals of the
message, but is not itself confirmation that a valid logon handshake has
taken place.  Maybe you sent out a Logon, but have not received one
back.

onLogout, again, means you are done for sure.  And unlike Logons, this
could happen without any Logout messages as all.  The network may go
down for instance.

So in the end, onLogon and onLogout is what you should rely on to know
if you are truly logged in or not.  The messages are used in part to
determine these states.
