Re: [Quickfix-developers] Unexpected resend request behavior

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I believe the issue is the order of execution in the =
Session::verify(const Message&,bool,bool) function.  Shouldn't the =
conditional that resets the resendRange be invoked before calling =
doTargetTooHigh?
