Referrer parameter vs URL parameter?

[Nicholas_Manojl]

Does anyone have an overview on the difference between a referrer parameter vs a URL parameter?

I ask in the context of the form builder allows fields to accept a URL parameter (which I understand perfectly well), and also a "referrer parameter" which isn't well documented here (Set a Hidden Form Field Value - Marketo Docs - Product Docs )

In what way is the referrer parameter different to a URL parameter?

It's simple.  They both refer to URL query parameters. One looks for the param in the current URL, the other looks for the param in the referrer URL.

Of course, you can't expect an https:// referrer to exist on a non-HTTPS page.
