[Quickfix-developers] basic questions - difference between ThreadedSocketInitiator and SocketInitiator

[<laz...@gm...>]

Hi again,

I am new to QuickFIX and I have some basic questions regarding QuickFix:

1) Considering that at one time, there will be only one fix session
between an acceptor and an initiator. I do not quite understand the
purpose of ThreadedSocketInitiator and ThreadedSocketAcceptor classes.

Or do these classes exist to facilitate multiple sessions, in which
multiple "initiators" can talk to different acceptors and vice versa?

2) Does QuickFIX has some kinds of message persistence, for example,
what happens if the message is lost in transit? Does the engine takes
care of resending the message?

Thanks in advance. :-)
