Store non-member data?

Is there a way for a non-member of a website to have their information stored on the request form?
The issue we're having is people are downloading multiple items and having to fill in all the information every time.

We've had to customize the documents seller so far to not start the download instantly, email a download link and include a captcha, because we were getting bogus information spammed into the fields.

Is there a way to store the user's data for the current session in a cookie or something similar?

Hi

Yes, if you know programming, I think you can edit the code of the component to store the user data in session and then re-use that data when they download the document for the second time .
