You could store the state of the web pages in a form or URL variable. Then use that form or URL variable in the pages that follow to build a "back" button/link. This example:

href="myscript2.cgi?ref_page=myscript1.cgi&ref_action=get_fractals"
[download]

shows the link that could be used to get from web page one, to web page two. Once at web page two, the CGI can look backwards by parsing the ref_page and ref_action variables. This could be used to move the user one page back.
