[Quickfix-developers] Request resend

[Fad <s.f...@gm...>]

In the Fix specification there is written:

Upon receipt of a Resend Request, the resender can respond in one of
three ways:

1. retransmit the requested messages (in order) with the original
sequence numbers and PossDupFlag set to "Y"
2. issue a SeqReset-GapFill with PossDupFlag set to "Y" message to
replace the retransmission of administrative and application messages
3. issue a SeqReset-Reset with PossDupFlag set to "Y" to force sequence
number synchronization

With QuickFix is not possible implement the first point. Infact, the engine
doesn't allow to send message with MsgSeqNum small as regards the last sent
message.

Thanks.
