Context Infrastructure

Both Supply-Side Platforms and Demand-Side Platforms use Context Provider to retrieve data about Users, Sites and Devices.

Supply-Side Platform and Demand-Side Platform need to independently decide which instances of Context Provider they trust, and then independently query them. Even in case Supply-Side Platform and Demand-Side Platform choose to trust the same instance of Context Provider, they need to query it separately.

Context Provider needs to track Register Events. Thus, Supply-Side Platforms and Demand-Side Platforms need to share with Context Provider all the Register Events that they receive.

In response to a Register Event notification, Context Provider returns a Context Script, and then receives the results of this script being executed by a Supply-Side Agent within its sandbox.
