Description

When a third-party code is added to the publisher's page, the third-party can write to the shared storage of their own origin, or write to the publisher's origin.

Using a script tag allows the third-party code to be injected in the publisher's context, and using an iframe to load third-party code allows third-party to write to its own shared storage.

Code

• Code for third-party to write into its own shared storage
