need help writing HTML where the user inputs their email address to access/download files.

After submitting their email address, it can either take them directly to the pdf file or be redirected to a "Thank You" page that has a link to the file.

We would then be able to see a list of the email addresses & who downloaded what.

Also where in the code would the link be attached? Dont know if that makes sense to ask?

Does Java need to be incorporated into the code? if so how?

So confused please help!
