How This Demo Works

📰 Site A & 🛒 Site B (First-Party)

Each site sets its own site_a_visitor / site_b_visitor cookie with SameSite=Lax. These are first-party cookies — they can only be read by the site that set them.

📡 Site C — The Third Party

Site C is embedded inside Sites A & B via an iframe and a tracking pixel. It tries to set a tracker_id cookie with SameSite=None. Whether this works depends on your browser's third-party cookie policy.

🔬 What to Observe

  • In Chrome: third-party cookies may still work (check chrome://settings/cookies)
  • In Safari/Firefox: tracker cookies will likely be blocked
  • Try the SameSite toggle inside each site to see how Strict, Lax, and None behave
