In one embodiment, at a packet-forwarding engine for receiving packet flows and conditionally routing packets in the packet flows to one or more applications, a method includes receiving from a particular one of the applications a request that requests the packet-forwarding engine not to route the particular one of the packet flows to the particular one of the applications and identifies one or more conditions for routing particular ones of the packets in the particular one of the packet flows to the particular one of the applications. The method further includes, receiving a particular packet in the particular one of the packet flows, determining whether one or more of the conditions for routing the particular packet to the particular one of the applications are met, and routing or not routing the particular packet to the particular one of the applications based on the determination.
