NGIN-13: The notice URL (nurl) param of the OpenRTB request is now being respected and fired off. In the case of video where the nurl is only present and no adm, the VAST is pulled down from the nurl in reverse proxy fashion before being served to the user. This could be a LiveRail tag ect... The last thing we will add is the ability to copy paste LiveRail VAST URLs in the demand dashboard directly without getting the VAST XML.
