[Quickfix-users] How to prevent sending NewOrderRequest in response to ResendRequest

[Sumit K. <sk_...@ya...>]

Hi,

I am using quickfix 1.10.2.

When my client receives a ResendRequest from the other
connecting party the messages within the requested
range are relayed back.

If the NewOrderRequests or OrderCancelReplace requests
are relayed back to the other party (and are
processed) it might result in a risky situation of
duplicating the orders.

To prevent this from happening, I wanted to filter out
these messages while responding to ResendRequest from
the other party. 

I might be able to select (using toApp) and crack the
NewOrderSingle (and OrderCancelReplace) messages and
determine them to be duplicate messages, But how do I
prevent them from being sent again?

Additionally, what should be the right course of
action considering both the connecting parties. 

Thanks

Sumit Kumar
