Hello,
I too am trying to figure out exactly how Eloqua cookies are working, and more importantly a way to clear Eloqua cookies on a <button> click.
Use Case: Customer A forwards email to Customer B, Since the Eloqua cookie is set in the email for Customer A, when Customer B clicks on a link in the email, our landing page is wrongly identifying Customer B as Customer A due to the cookie set in the email.
We want to give customer B an option to "sign out" and feed them a new form.
