 The following is Prebid's way to setup bid request for long-form, adapters are free to choose their own approach.
 
-Prebid now accepts multiple bid responses for a single `bidRequest.bids` object. For each Ad pod Prebid expects you to send back n bid responses. It is up to you how bid responses are returned. Prebid's recommendation is that you expand an Ad pod placement into a set of request objects according to the total adpod duration and the range of duration seconds. It also depends on your endpoint as well how you may want to create your request for long-form. Appnexus adapter follows below algorithm to expand its placement.
