Reproducing SameSite=None > SameSite=Lax

• Create certificate files in myssl/:
  • public.pem
  • private.pem
• Start the container:

  docker-compose up -d

• npm install
• Run the tests:

  npx playwright test

The test will fail; although SameSite=None is returned in the Set-Cookie header, the cookie is set with sameSite: Lax.
