Storage Access API Demo!

Set Cookie screen!

Using this demo

  • Ensure third-party cookies are turned off:
    • For Chrome this is done by setting: chrome://flags/#test-third-party-cookie-phaseout
    • Restart your browser to make that flag takes effect.
    • For Firefox and Safari this is already the default.
  • Set the value of the foo cookie using this screen.
  • Then, open this link and confirm you can read this cookie you just set in a third-party iframe embedding pages from this origin, on another origin when using the Storage Access API.
