Slot position in pod value -1 means Last ad in the pod
The last slot of the pod, just before the content resumes.
When to send it
On a request, send -1 in Video.slotinpod or Audio.slotinpod when the impression is guaranteed to be the final ad of the break, right before the content resumes. On a response, a bid with Bid.slotinpod -1 is only valid if the seller places it last.
Last position is valued because the ad runs next to the returning content, when the viewer is waiting for the program. It is confused with 2 (first or last), which is a weaker guarantee, and with Video.podseq -1, which means the last pod in the stream rather than the last slot in a pod.
