Does JotForm suppor tracing the incoming request from (e.g. website)?

Thanks, Paul

Thank you for contacting us.

I am not quite sure if I understood your question correctly. In case you would like to catch the page the form was filled out, there is a Get Referrer widget that can be added to the form.

If you are referring to something else, please provide us with some additional information.
