We recently upgraded to 10.0.0, and switched URL mode to modern with legacy 301 redirects. We are noticing that if someone goes to a legacy affiliate link to default.aspx, the affiliate id is stripped from the displayed URL, and there is no confirmation that the URL has been applied.
How can we confirm that a session from a non-logged-in person is being tracked with that ID?
How can I confirm that an abandoned cart came in on that ID?
How do we construct a link appropriately for an affiliate to a page on the site?
