User Navigates to a Site

The following diagram presents the details of the workflow that takes place when a User initially navigates to a Site:

Here are the main steps of the above workflow:

• Supply-Side Agent notifies Supply-Side Platform about Register Event.

• Supply-Side Platform returns its Context Script, and Supply-Side Agent makes an attempt to execute this script within its sandbox.

• Using an endpoint contained in the Context Script, Supply-Side Agent notifies Context Provider about Register Event.

• In response to the Register Event notification call, Context Provider returns its Context Script, and Supply-Side Agent makes an attempt to execute this script within its sandbox.

At this stage Register Event is only reported within Supply-Side Platform. To keep both sides in synch, Register Event will be distributed to Demand-Side Platform in the next step.
